Rotation options is what I'm seeing, and that is a good thing. The one guy that should be mad about this move is Young. Obviously, Allen will be taking snaps away from him, probably a lot, but I could really see a scenario where Young, Houston and Allen rotate constantly, so they all get roughly the same snaps. Maybe moving Houston inside on possible passing downs, if he keeps his weight around 300.
Hell of a move by Emery out of the Blue, the guy has yet to not surprise me in an off season. Now this doesn't let him off the hook in the draft but hell of a move.
