They'd have to be incredibly high on Bradbury to take a center. They have too many other needs in terms of guys to develop. They strongly need a Guard - or a tackle who can play guard. They obviously think they need a safety. A cornerback with a chance for a high end would be extremely nice. They need a DT. An edge rusher. I suspect they would like an RB and a QB to develop. A TE since Higbee is a free agent after this season, and they take a while to develop usually. Frankly, unless they are lying about liking Allen, center is way down the list of needs. They just don't have enough picks for the positions they need to develop. Center is ahead of punter for need, I suppose.
I'm still amazed at that mock that had the Rams taking a center in the first. I know it's hard to be familiar with every team, but didn't the writer think "The Rams wouldn't have cut Sullivan, unless they had some replacement in mind"?
