I'm going to have to presume you didn't see the game. (big surprise) If UL "dumbed down" the O for a "lesser" Qb, they sure showed tremendous confidence in him on the first drive of the game by allowing him to pass on 5 of the the 11 plays in the drive.
Personally, I think uL got their comfortable lead, saw that Cantwell was taking some shots standing in the pocket, and figured the risk of losing another QB to injury, in an OOC game, on the road, far outweighed the reward of having 45 points on the board.
To me, that doesn't constitute dumbing down. For that example, one only needs to look at Herm Edwards game plan last week vs the Donx.
