Something I'd add to the Rams list of needs is receivers who read the defense better. Or at least read it the same way the QB is reading it. Pre-snap reads, protection calls, a quick release and good blocking are all important but equally so, IMO, is a receiver who understands the situation and adjusts accordingly. The end result for Manning wouldn't be positive if his receivers weren't adjusting and catching the ball like they do. Which I think has been a huge liability for the Rams in recent years. I've seen Sam do some of those things that Manning does right up to the point of releasing the ball but then the receiver doesn't do his part. Not saying every, single, time or that Bradford has been flawless but I think that's a big part of the continuity problems that the Rams have had.
I think Bradford's become more hesitant at times because of his distrust in the receivers. Not just on blitz reads but his guys often don't seem to be seeing the field the same way as he does. Which you can't say about Manning and the Broncos most of the time.
