This could definitely make for an interesting game next year. I think King/Samuel pick up the slack quite fine at RB, but I have no idea who they will have for QB. 4 guys will fight for the job but all have huge downfalls. Southerland is also gone and he's a huge piece of their offense. They also lose MoMass, Harris, and Goodman. They'll still have weapons, specifically Green but it's alot easier when you can double one guy and stack the box. Their OL should be stout though, barring injuries since they return everyone.
On defense, they lose 3 of their starting DL but retain everyone else at those positions. They also return all of their LBs, save Ellerbe. In the secondary, they lose Byrd and Brown but return everyone else. The defense should be stout. They will also be breaking in a new punter.
