Barker's made several mistakes in this game. I never said he was perfect, haven't even said he's good. He hasn't played enough to make that determination. Before Towles was pulled, it was 3 and out, 3 and out, Barker came in, led us down the field in 5 plays and we scored. Did that not look like a different team? Receivers were catching passes, unlike before that point in the game, the offense moved the chains and actually scored.
Again, take into consideration that at the time when that post was made, that's all that had happened with Barker, he was 3/3 with a TD, and Towles was 5/17 with an INT and 2 failed series from inside the 5 yard line.
