Additionally, if you weren't adjusting to what the defense was showing pre-snap...setting up for failure.Yes, agreed.
So all this being said, I'm incredibly optimistic about next season. I assume Mac isn't "broken", but rather that he performed poorly in a terrible, awful situation, and that it's very fixable. I wonder also whether some of what we saw as terrible O-line play was actually the result of this bad coaching. As in, we think the players just sucked, but if they weren't even getting practice reps doing the things they were being asked to do, how do you expect them to perform well?
I still think they need some talent upgrade, especially on the OL, but man, my level of optimism for next season has gone up considerably.
That said, lots of NFL teams have offensive coordinators and still ain't good, so we'll see.
