My observations after doing half a dozen mock drafts myself, is that there were 'name' edge defenders into about the 3rd round. Defensive tackles almost as plentiful. But offensive tackles dried up quickly.
I think football players today that have linebacker size are not opting to learn the traditional off the ball linebacker positions, the money is in the edge rusher. So you see a lot of tweener edge guys 6-2 230 in that role.
