If you're the Ravens, who would you rather play against, Allen or Peterman? Which QB scares you more?
Allen should start, assuming what we say on Sunday with the OL isn't going to be a normal thing.
Like others have said....if you play Allen, that's it - he's the QB. No turning back.
If the OL really is going to be the disaster we saw against Cincy, then I can certainly see starting Peterman for 4 games...then, when he inevitably lays an egg, Allen comes in and it won't matter what he does - he'll just be better than Peterman.
If, however, Allen starts game 1 and goes 0-4....yikes. Not sure what happens then.
