That play is the beginning of a counter bash option and the failure was in the protection call. JT is right to be confused because Bradbury was never going to be able to reach Rousseau (I assume that is him because I can't see the uni #) in time for the trap block. This play failed before it even started. And asking Maye to recognize this sort of red flag, i.e., putting the onus on him to audible out, is asking too much of him at this point in his career.
You don't try to get too cute on protection calls against an elite DL, especially with a 2nd year QB.
