At #20 we're at the tail end of the good OTs. I'm not convinced that the center's this year are all that past the first couple. And because of how we've managed FA we NEED to take a center that will start and while we have OTs, we would be so much better with a quality addition at RT.
Worst case scenario for me is taking a WR/CB in the first as that leaves us forcing things in the later rounds. I think we go OL/OL in round 1 & 2 and then pick up what we can. I do like the idea of Ruke Orhorhoro being drafted as a Cam replacement though but I'm not sure that we can afford to do that this year.
