This is all off the top of my head, so take it with a grain of salt.  If I do it right, norcalfella may give you his more thoughtful list.

(I wrote it up last night, but managed to lose it...so I'm writing more concisely/impatiently, this morning.)

1. LaDainian Tomlinson - Seeing him out-accellerate track stars, stiff arm 250 LB's to the ground, and then change direction to juke a guy out of his shoes...in his prime, he was in a different league.  I don't know how many people realize that.
2. Peyton Manning - Fastest read of the field of any QB.  And then he delievers the ball exactly how he needs to.
3. Brett Favre - I wish he weren't playing, anymore, although it did get me to listen to what an encouraging guy he is.  Also, the master of "making something from nothing."
4. Marvin Harrison - So in synch with Manning, and so subtly talented at causing defenders to miss, that it was deceptive how good he was.
5. Michael Strahan - Mr. gap tooth scares me, and I'm not even on the field.
6. Tony Gonzalez - Not only the best TE of the decade, but one who became a pesce-vegetarian at the end.  (Which makes me happy.)
7. Brian Urlacher - May not be the player Ray Lewis is, but is twice the leader.
8. Shane Lechler - What is a punter doing here?  Being the best punter for most seasons of the decade.  If you don't think that matters, look at how the ball ends up positioned.
9. Champ Bailey - Very effective for a little guy.
10. Larry Fitzgerald - I feel bad about putting him here...the next few years will tell whether I was overly optimistic, or prescient.

Notably absent:

• Randy Moss: If he played every game as well as he could have, he'd be up there with LaDanian (who I can't call LT....just can't.)
• Terrell Owens: Impressive, but a nutcase.
• Tom Brady: Am I nuts?  I think he was surrounded by a team, and on a lesser team wouldn't even be mentioned.
• Warren Sapp: Jerk.
• Ty Law: It's been too long, and I've forgotten how many seasons he was a stud for.
• Edgerrin James: Was very good.  But I could have run 1 yard behind that OL.
• Kurt Warner: Fluke.
