Fantastic news.
I've been advocating keeping all of our D-Lineman until we absolutely, positively have to cut them just because injuries can happen at any time during the offseason/training camp.
The only exception to this is Dwan Edwards, more for his own sake than anything else. If the Bills are truly going to be a base 4-3, I say cut him now and give him a chance to sign on with a 3-4 team.
