Nah, some people in this thread and others have pretty much taken the position that it's unfair to blame Prescott and that in fact, it was the OL, the WRs and RBs who played bad and let Prescott down. If they had played better, Prescott would have been magnificent.
Even you kind of do it with your last sentence, when you say Dak's play could not be further from the reason we lost this game. Actually it's one of the prime reasons we lost this game today along with bad OL play. Even when he had time, he made some bad decisions with the ball and some really poor throws.
