Thankfully we don't have this problem.
Its definately a tough question. OT is out of the picture because you do not waste a #1overall on a RT. A QB is not needed.
I do not believe that Curry would be chosen due to the fact that LB's are really never chosen in the Top 3, let alone #1 overall. The value is just not there. Unless we were convinced he was the next Ray Lewis he is not going #1 overall, just do not see the value there. I could see us scrambling to trade out of the slot for either Curry or Raji.
But if we were stuck with the pick, by process of elimination I believe it would be Crabtree.
