I almost think the ref thought the clock expired and thought there was no point to bring the ball back.
That play call was even worse. An empty backfield, where everyone in the known universe knows your shaky young QB is going to throw?
I would like to see him with another coordinator. I think the playcalling is actually worse than the QB.
Coaching decision wasn’t bad, anything could have happened forcing the punt, a good return, shank, block etc. If you had any other QB than Zach that might be workable. Need to be able to throw a corner route out of bounds though. I ve seen Mahomes and Allen score in less.
