It is actually educational about how routes should be set up and how QBs should be reading a defense.
While Zach was not at fault on several plays, there were several where the play worked as designed and he either missed the throw due to poor fundamentals or he missed the read he should have made.
One of them would have led to an easy TD pass, but instead he missed the big play and scrambled for a short gain.
While Zach is not at fault for everything, he is a big part of it, and it isn't all on the OC either. But yes, there is blame all around
