What level of perfection do you consider acceptable? The faults you're finding occur with pretty much every starting quarterback in the NFL. "Pocket awareness" is possible only if a pocket exists to be aware in. Did you see Aaron Rodgers "poor pocket awareness/missed check downs/tuck and runs" vs. Buffalo last night? Mac's decisions running the ball were praised by BB, by the way.
Mac played OK yesterday under the circumstances -- not great, not terrible. He was rusty and understandably had trouble with timing under pressure. The nullified pick-6 was a bad pass on miscommunication with Meyers that should not have been thrown, but even the GOAT has committed that cardinal sin multiple times.
Here is how Mac should be evaluated going forward: (1) does the team win and (2) does the quarterback commit avoidable errors contributing directly to any losses. The latter has set a clock ticking in East Rutherford, N.J.
