Tate seemed to have a perfectly good relationship with Kirk. More of the strain there was between Tate and O'Keefe.We had "open" competitions until this year. Mobile QBs can be in the room, but remember it takes the average QB 1+ years to learn the oh so complicated juggernaut offense Iowa runs. The staff has always gone with who manages the offense, Drew Tate was 1st QB to really go off script and cause KF a bunch of grey hair.
Also, the difficultly has less to do with the O and more to do with the responsibility that WAS heaped upon the QB. The QB was essentially getting trained to be like a coach on the field. Thus, the expectation was for the QB to be able to read the D and then identify from that read what was the right play to get into based upon that read. After that, the QB then still needs to make decisions post-snap - determining what looks to exclude and what to focus upon. And, through all that, go through his progressions and be smart about ball-placement.
From what I understand, both Petras and Padilla are/were really bright guys. However, part of the problem with guys like that is that sometimes they worry too much about being perfect all the time. It can lead to the standard paralysis by analysis situation.
To exacerbate things further ... over the past 2 years the blocking has obviously been bad. That makes guys who were probably already suffering from paralysis by analysis ... make them feel "rushed" ... even more a recipe for failure.
Lastly, as a educator, I can tell you that post-covid ... a bunch of kids out of high-school are weaker than they've been in the past ... both due to covid-related psychological stress AND due to the fact that far less was expected of them (in high school). I've seen that negative impact this had made on their academic achievement ... so I it seems reasonable that it could effect (some) athletes too.
Anyhow, to my understanding, some changes have been made to the O in terms of how QBs process things. Supposedly, the changes are supposed to help things get processed easier and faster. That remains to be seen.
