I say Hampton's got 5 years left in him. He doesn't have to move more than a couple yards if that per play. Dude just has to be strong and anchor. And until we have someone that can replace him, I'd want to keep him around.
If your DLine is Hood, McClendon, Keisel, every one of those guys can be blocked by 1 player. Then Wood or World get doubled and we can get no pressure on the QB. The NT is the key to the 3-4. I'm not going to be surprised if our D has some challenges without Hamp.
