QB's - AFC, hands down. Peyton, Brady, Palmer, etc... The NFC has Bulger, Brees, and Hasselbeck, good, but not Peyton and Brady.
RB's - AFC; LT, LJ, Travis Henry, Maroney while the NFC has S. Jax, Gore, and Shaun Alexander. I'd go with the AFC again.
WR's - I think the NFC gets the nod here - T.O., Steve Smith, Driver, Roy Williams, Fitz and Boldin and Holt. The AFC's Marvin, Reggie, CJ, and Javon are the cream of the crop in that conference, which may be better at the top, but as a whole, I think the NFC get's it.
TE's - NFC East may have better TE's than any conference - Shockey, Cooley, Witten, and LJ Smith when healthy.
Best D's - AFC, no doubt, Baltimore, Denver, San Diego and New England are all super bowl picks because defense wins super bowls and these are 4 of the top 5 defenses.
Best O's - AFC again, offenses win super bowls and most of the aforementioned teams have top O's. Then add Indy and Cincy. Who does the NFC have, New Orleans?
Best Coaching - New England, so the AFC
Best Rookies - I don't know because none of them have played yet. But, I heard a good reason why the AFC is so much better than the NFC lately and that's because while San Fran, Dallas, and Green Bay where winning all those super bowls the AFC sucked and where scooping up top draft picks. With that reasoning, it seems that while the AFC has been beating up the NFC so badly lately, the NFC is getting most of the top draft picks and the NFC should rebound. It's a cyclical thing. So, since I agree with that analysis, I'd say the NFC should have the better rookies.
Criminals - AFC - Bengals and Titans win that one alone. Tank out of the NFC and then they have the most high profile one in Mike Vick, but the Bengals should win this category alone.
