I've never gone by Kiper's rankings. He's just as bad as some of us who only spend maybe a couple hours a week rankings players. Heck last year he had both Jason Avant and Elvis Dumervil in his top 25, projected as first round picks. Both went in the 4th round. Jason has 7 receptions on the year for the receiverless eagles and while Elvis Dumervil has 8.5 sacks on the year, he has yet to start a game and only comes in on obvious passing downs. I personally have Kyle Young as my #1 center, but that's only because I like the big nasty centers. He's Andre Gurode with more muscle.
