There was a stat out there that we were the only team in the NFL without a pass longer than 30 yards (or something like that). Not yards after catch, but an actual pass longer than 30 yards. That makes it really easy for teams to shut us down and makes Forte's performance that much more amazing.
We need a QB that can stretch the field. Orton is great for game management, and he won't lose many games on his own, but he won't win many on his own either.
The WR situation clouds my judgment, because it is hard to judge how Orton performed with that sorry excuse for a WR corps.
