Actually, I think this is a huge part of the problem.
I get the idea of requiring players to be flexible from a morale standpoint and it makes good sense in the OL and DL; Paul did it there as well. For the skill positions, I'm much more concerned. In a new O what the skill players need is consistent reps for their position, not a requirement that they know what to do in 2 - 3 of them. The "competition is king" meme makes it even worse; the players think they have to be equally efficient at multiple positions to keep on the field. I hope Coach stops this soon. Not, mind, that he'll say he's stopping it; just stopping it.
