Look, the entire offense -- plays, calls, checks, is designed for EJ Manuel. You can'r reconstruct and tailor-fit the entire game plan to a new QB in 4 days of practice. The offense will open up under Orton but it will be a gradual process.
Yes, I know it is painful to watch CJ slam into Suh over and over but give the Lions some credit. They are ranked as the #1 defense for a reason, and their DL is at the top of the league.
