Sounds strange, but I think drafting a Center could be our #1 priority going into the draft, barring an unexpected move in free agency to sign a quality starting guard.
So here's the situation:
The 49ers hope that Kilgore can start at RG in 2012, but there is considerable risk in that proposition. Snyder is gone, so we're walking the tightrope without a net. We're trying to bring in a vet guard on the cheap to compete with Kilgore, but a more likely scenario is that we draft an interior lineman in the first three rounds that will directly compete with Kilgore -- winner starts at right guard. Center is the need -- not a pure guard -- because we need a center of the future anyways. And if Kilgore wins the RG competition, we're stuck with a high draft pick guard. Furthermore, almost any center can also play guard -- it's an easier position to play.
Clearly, Peter Konz at #30 would be an optimal scenario -- and it may even be worth it to trade up if he's there; I expect Chicago to trade down in order to make up for the Brandon Marshall trade -- a 3rd round pick is about enough to pull it off. If we decide not to trade up for Konz and he doesn't fall to #30, we can get Ben Jones at the end of the second round, or Phil Blake or Mike Brewster in the 3rd round.
If I had my way, I'd try to ensure that we snag Konz, no matter what. If that fails, I would take Ben Jones in the 2nd -- Jones has a very high "floor" and can start as a rookie.
