This one you have to break down by AFC and NFC. The AFC vote clearly goes to Peyton Manning, or how about the Hunter Smith. Special teams are so vitally important in the playoffs. He is the only kicker you can say who hasnt done anything to hurt his team. But seriously, its Manning.
In the NFC its tough, Carolina showed alot of grit but the gameball cant really go to a unit in the fairer sense of the award. So it has to go to McNabb, he started off pretty weakly but overcame that and had a heck of a game. Around 250 passing with 2 tds, 107 rushing, never done by a quarterback in the history of the playoffs ever! And had many clutch throws throughout the game. Most obvious the 4th and 26, but would that 4th and 26 even matter if he didnt break 2 1/2 tackles that would of resulted in a sack to find Pinkston in the front corner of the endzone with a laserbeam accurate pass.
Overall the award would have to go to McNabb solely on the basis that he doesnt have the weapons to worth with as does Manning and a case could be made that the Packers Defense is better then Kansas Citys especially of the last month plus.
