The Bills were in an untenable position with Jason Peters. The tight end-turned-Pro Bowl left tackle wanted a new contract, the team wasn't interested in renegotiating, and they wound up sending him to Philadelphia for a first-round pick a few weeks before the NFL Draft.

Armed with two first-rounders -- Nos. 11 and 28 -- it was only a question of when the Bills would draft Peters' replacement. The answer, it turns out, was never. With Michael Oher still on the board, Buffalo took Aaron Maybin and addressed another big need -- pass rusher.

The Buffalo Bills seemed destined to acquire a pass-rusher on the first day of the NFL Draft, and their 11th overall pick was a perfect place for that: with Tyson Jackson, Everette Brown and Aaron Maybin all available, the Bills weren't going to have a problem there.

Now that Matt Birk has chosen the Ravens, Minnesota has to move on to Plan B. But the good news is that this is a very good year to be trying to replace a center.

The Vikings had been planning for the possibility of losing Birk since before the 2008 season. They already have 2008 sixth-round pick John Sullivan as a potential replacement and theoretically guard Anthony Herrera could also slide over and play center, but if the Vikings want to bring in some competition, the 2009 draft class is one of the best classes for centers in years.

In the Sporting News Top 99 draft prospects (released today at Sporting News Today), four centers are listed among the Top 99 prospects and ESPN has three centers in the top 65 on its board. If the Vikings aren't completely comfortable with Sullivan, they could snag another center in the draft and use it to not only give Sullivan competition, but in the case of a prospect like Max Unger or Eric Wood, it could also give them some improved depth at guard, and in Unger's case, tackle as well.
