This is a good idea.  I think Rox Girl was going to do one of these later in the week, and will have far more stats to back up her comments.  I'll do mine position by position.
Overall the Rockies led the NL in hitting. And we set an all time MLB record for defense (fielding percentage)

1B: Todd Helton. Isn't the power hitter he once was.  Not the hitter either.  But he fouls off pitches, until he gets a walk. OBP is still up there. Great D. Should win another Gold Glove, and he's a BIG reason the Rockies set the all time record for fielding %

2b: Kazuo Matsui.  Has been reborn in Denver. He has great range defensively.  He hustles on hits. He makes good contact, runs well.  Switch hitter, a little better from the LH side. Average ok from right, but no power. The Mets run him out town..we have a Matsui fan club! "It's hard to rock a rhyme that's right on time...It's Tricky!"

SS: Troy Tulowitzki. Hard to even know where to start.  GREAT defense. Range up there with Jose Reyes/Jimmy Rollins. Cannon for an arm. He makes plays that I've never seen been made. Has been a solid hitter, especially in the 2 hole when Willie T (avares) went't down.  Has gotten better all year as a hitter. Set record for HR's for a rookie shortstop.

3B: Garret Atkins.  He's a pure hitter, with a swing that is unslumpable...which went into a 2 ½ month slump.  Has been hot since.  He's not a power hitter, but a line drive, gap, solid contact, hit it were it's pitched guy.  The most under-rated guy in the NL in my opinion. Defensively his stats are average...but he's inconsistent, and a little stiff. Brooks Robinson he ain't..

C: Yorviet Torrealba.  Great leader and handler of the pitchers. A smart catcher, he's a big reason for our staff's success, especially the young Hispanic kids. His bat is ok for a catcher, but he's been HOT during this run, and has the knack of getting the big timely hit. He has a candy arm.  I could steal on him. He's Josh Bard bad. It doesn't help our pitchers don't hold runners well.

RF: Brad Hawpe.   Has a lot of pop.  Very streaky power hitter.  Couldn't hit lefties at all...then when forced out of a platoon when Willie T went down, and Spillbourghs was forced over to CF...he started to KILL lefties. Doesn't take great routes to fly balls, but makes up for it with a Cannon Arm. (lead NL OFs a couple years ago in assists..now no one runs on him much)

CF: currently a Righty/Lefty platoon of Ryan Spillbourghs, and Corey Sullivan.  Spilly is a nice 4th OF type. Nice bat, good range, good arm.  Has gotten cold with playing almost everyday.  Sullivan, is a great defender, plus range, plus arm, but thought he was Dante Bichette..now he's more of a contact hitter.  Willie Tavares may be back for this series. He has/had a quadriceps injury.  Speedster...slap hitter, bunter, covers lots of ground in the OF.

LF: Holliday.  He's a stud, an All-Star. What do you say about the guy that lead the league in average, and 2nd in RBI's?  Defense is ok.  Still takes bad routes to balls at time.

Bench:
C: Chris Iannetta  Rookie Catcher. OK D. Bat is unknown commodity still.
1b/3b/OF Jeff Baker. 1st choice for righty PH.  Has some pop.  D is shakey at best.
2nd/SS/3b/OF Jamie Carroll (not JIMMY ESPN!) great year in 06..bad year hitting in 07.  Solid D with plus range but not spectacular, has been a defensive replacement for Atkins lately. Hits ok (barely) no power.  
OF Seth Smith Lefty PHer.  Was in AAA until Sept. 15, late call up due to injury. Sorta-big time prospect corner OFer.  Hot as a PH got him on the post season roster.

Not sure who will be left off roster if Willie T does come back.  Could be Sullivan, Smith or Baker.

These are my Rockies stories:

I was at the game when Tulo hit is first HR last year, in San Diego. He monstered it over the left center wall, which is about 420 feet at sea level.

Last year right after the Kaz Matsui for Eli Marrero trade my dad and I were at a game in Denver and went early to watch BP. It was Spillbourghs first game after his callup and this guy next to me kept hollering for Spilly to throw him a ball. He kept yelling, "Hey Eli, throw me a ball. Eli, how bout a ball huh?" Spilly finally got tired of him and yelled back, "I'm not Eli, my name is Ryan!" Then he walked over to where Matt Holliday and Garrett Atkins were talking and told them what happened and Holliday took one look at him, spit out some sunflower seeds and said, "hey, go shag some balls won'tcha?"

Many people don't know it, but Todd Helton's beard has magnificent powers. It works to not only hit balls into the opposite field gap but it also attracts errantly thrown Garret Atkins throws from third base. Also when Manny Corpas' gatorade-gyro ball isn't working Helton uses the power of his beard to bend pitches towards the outside corner of the plate (Ryan Howard hates this power and tries to overcome it with his strong eastcoast bias and strong addiction to Jarrod's Six inch subway samiches).

Well, got some time tonight, suppose I'll fill in the blanks.

Rest o Bullpen:

Manny Corpas- Well, game's over.  About the only trouble I've seen him get in lately has a lot to do with infield singles.  Occasionally susceptible to a long ball, but not often in big moments.  Did you see the first Philly game?  There's no mystery, no doctoring here.  His ball really moves like that.

Jeremy Affledt- Man scares the bejesus out of all Rockies fans, because he's used as a lefty specialist and he's really not.  Was instrumental in the early part of the year, IMO got worn down and wasn't as effective.  He's good, but it's all or nothing with him.

Matt Herges- Not sure how he's come back from the scrap heap, but damn are we glad he did.  He's one of the long guys, one of the high pressure guys, basically he's done everything this year.  Has had maybe one bad outing this season, but we would not be here without him.

Taylor Buchholz- Well, a turbulent season for him.  Was in the bullpen, then in the rotation, then back to the bullpen, then injured, then back in the bullpen.  Various levels of effectiveness, but he was incredible in game 163.

Starters

Jeff Francis- Crafty.  Going to get some Cy Young votes, deservingly so.  Not a true ace, more of a two or three, but can be downright frustrating.  

Josh Fogg- Ah, Fogger.  He's a less effective righthanded version of Doug Davis in my mind, but that might be underselling Davis.  He battles, throws up any piece of crap he can, and comes out as a mediocre pitcher.  But somehow it works.

Ubaldo Jiminez- You guys are going to hate seeing him for the next couple of years.  Man can touch triple digits when he's pumped, and has some nasty breaking stuff.  He's young, has some wildness, you'll see at least one curve slip out of his hand and directly at a batter's head.  

Franklin Morales- Lovingly dubbed 'lil Johan' by some, again, just not a whole lot of fun to face.  Plus he's a lefty.  Has a higher ceiling then Ubaldo, and that's just sickening to think about.  Imagine keeping some semblance of our offense together, then adding these young fireballers to the rotation... yeah, we'll be in this position again.

Aaron Cook- Complete wildcard.  Gets pounded when he rushes his sinker, but is very capable, especially against your free swinging selves of having 5 pitch innings.  Don't know for sure if he's even going to be on the roster.

Well, that's most everyone... any questions?

I don't have stats, but I have my stories and chatter that comes from seeing a great number of games and spending too much (or not enough?) on this team. Just to give you an idea what these guys are like - only putting in the guys I've actually talked to.

oh by the way, hello, I'm Squeaky from Purple Row. Friendly visitor.

Lineup:

Kaz Mat: What's not to like about Kaz? He's gone through a cold streak or two and been injured once or twice, but the Flying Dragon (no, I have no idea where that nickname came from) has been awesome for us this year. He's signed a ticket and a program for me. He doesn't say much b/c of the language barrier, but he seems really nice.

Tulo: Tulo is awesome. He is so awesome you must say his name three times: Troy! Troy! Troy! I say this because at photo day, with my two older sisters with me, Tulo introduced himself three times. I thought it was highly amusing. Also, the chant that Coors Field has going for him is incredible - on Saturday it was so loud you could hear it echoing from the other side of the stadium. I maintain it is all Tulo's fault the Rockies figured out how to win.

Holliday: Also awesome in stats. Not the greatest defensively, it's true, but he works really hard on it and he's gotten ten times better since last year. Nice guy, not the brightest, but that's okay. He has a temper - don't hit him, or he'll be tearing the cover off the ball on its way to Mars.

Helton: Everyone knows the deal on Helton's baseball, but my story is from when me and my sisters met him on photo day - it was the last picture on our camera, so we decided to take it with all three of us and Todd. He says "come here" and drapes his arms around all three of us. the picture turned out incredible.

Atkins: Offensively, he's been unstoppable since June. Defensively, he needs work, but not to the point Jamey Carroll should be subbed for him in the seventh inning of critical games. He's a natural first baseman. I don't have any stories about him...seems pretty quiet. Except that he and Holliday are always together and chatting.

Hawpe: Bradley. Heating up against lefties, decent in right. Not too many heartattacks. Ridiculously good with 2 outs. Also very sweet and very much a redneck. Heh.

Spilborghs: My personal favorite. Genuinely crazy and fun dude (bought dancing robots for the clubhouse, has Gwen Stefani as his walkup music). At photo day, when my sister and i were taking a picture with Atkins, Spilly pops up in the background with a very cheesy smile.

Bench:

Iannetta: True quality as yet undiscovered - been pretty buried this season. Fun fact: he's a math major and has read The Elegant Universe, and even admitted to reading it when I asked him - I've read it, too.

Baker: Hot and cold streaks often. Pretty good off the bench. Really fun guy, very nice. Most of these guys are, actually.

Carroll: Not as good as last year. Always, ALWAYS out signing. if I had him sign something everytime he was signing and I was there, I would have his autograph about six or seven times.

Pitchers:

Hirsh: not sure if he'll be joining the team for the NLCS, but I want to mention him because he's another really cool, outgoing, kind of crazy dude. And, to you "Team Jesus" people (I don't accuse anyone on here of thinking that), Hirsh is Jewish and said he has never met a more welcoming group of guys. So there.

---

Hmm...I'm sure I'm forgetting a few. I should mention Corpas is amazing, Fuentes is a daily adventure, as is Affeldt, Jimenez and Morales are the young fireballers and are called so with good reason, Redman is a rollar coaster every pitch....and that's all I can think of. Basically, these guys are fun, a little crazy, and they really root for each other, which is nice to see...kind of like the DBacks in their makeup.

Look for the little boy waving his arms like an Angel and kick him out of the stadium. It is uncanny how a single team can get so many breaks for so long. Timely balls hitting the foul line, dribblers for hits, a gazillion diving catches, beneficiaries of wild pitches and timely walks. Don't get me wrong, they are a very good team, but they are playing way above their heads. This little streak is so absurdly ridiculous that if they do pull it off, they might get their own exhibit at the Baseball Hall of Fame. It's hard to win when you have to fight the other team, yourself, and the other team's luck.
