For one, it's more helpful to see the juniors, seniors and occasional draft-eligible sophomores all together, just as you see them in the NFL draft. Second, trying to watch enough football and talk to enough evaluators to readjust the rankings every week just got ridiculous.
So here goes with the first version for the 2013 season. The Big Board, of course, will still be updated each week. Below, you have the defensive tackles.
Note that one asterisk denotes a junior; two asterisks denote a draft-eligible sophomore.
A rare defensive tackle who projects to operate as a two-gap, zero-tech nose tackle in a 3-4 ... but Nix also will show off the quickness to be a 3-technique penetrator in a 4-3. He has a great initial burst for a man his size (in the neighborhood of 340 pounds), and if he gets an arm through he can clear blockers and penetrate. Could be a little more disruptive against the run, but he's going to get better.
