I hadnt really thought about it until i read the article linked here, but this is a big area of concern if we sign manning:

Five thoughts on Redskins signing Manning | Washington Examiner

4. The offensive line's strength does not mesh with a straight drop-back passing game. The Redskins' line is built to block on the move and is helped by play-action and bootlegs. But Manning made bad and mediocre lines look good in Indianapolis with quick decision making. If he's in a system he knows well and with players he's comfortable with, that should continue. However, it should increase the need to find a right tackle in the draft eventually to replace oft-injured Jammal Brown. Of course, that could happen anyway.

If we get manning, we may not have the right type of offensive line to protect him. So lets just say we change our OL philosophy and overhaul the line (including drafting a tackle in the 1st round) to better suit a straight drop-back passing game. What do we do when manning retires in 3-5 years? get rid of the line again and go back to a more shanahan-esque line with smaller, more athletic guys? or stick with the manning-esque system so we keep the line in tact? As much as i love the idea of manning in the B&G, these concerns are really making me reconsider my position.
