A timing and rhythm offense looks very different when your QB struggles with timing and rhythm. My point is that I think Kliff calls it close but the execution looks very different depending on if it is McCoy or Murray. That isn't to say that Kyler runs it worse, just that he runs it outside of script.
i think this is the case.
re-watching games, it seems like:
when coverage matches pre snap read, ball comes out in rhythm.
when coverage doesnt match pre snap: he holds and waits for people to uncover rather than moving to his secondary read
dont know if this is an experience thing, or, who he is.
also what I noticed re-watching games: K1 covers up a lot of shaky pass pro
