It's a popularity contest. I don't think the Pro Bowl has EVER been the "best" players in the league...only the most popular.
With all the hype around Vick (even though I agree, he sucks) it's hard for him not to get a majority of the fan votes. Every time they [Falcons] play all the announcers do is suck Vick's cock. It's quite bothersome.
I am glad to see the Barber twins in it.
