Even TL himself once talked about being “outvoted” in terms of certain play calls this season.
I guess it all depends on the definition of “full control.”
That was a deep shot play that got vetoed.
Nobody other than the head coach has "complete control".
This doesn't mean that the coordinators aren't given what most would consider to be complete control.
Deep shots are something that a head coach is going to overrule from time to time. I'm sure Phil has had a couple blitzes and Lavar a fake punt overruled over the years. It's a head coaches job to manage risk according to time, score, field position.
It was immediately obvious this season that Iowa was running TL's offense.
There just isn't enough time to run two different offenses. TL still hasn't even fully installed his offense. There never would have been enough time for TL to have had continuously collaborated with KF regarding when he was going to run his own offense and when he was going to run an "Iowa offense" (that never existed).
It would have been far too confusing for the players to have been running two different offenses. Every single step a player takes has a purpose within an offense. Footwork has to be very detailed not only to execute a play, but to set up its counters within an offense. Each offense also has its own language. To try to combine different languages from different offenses is about impossible.
The play calls were coming almost exclusively from TL. There just isn't enough time between plays for coaches to be going back and forth about a play call. Especially with TL's calls that are heavy in verbiage.
Also consider KF didn't even coach the first game. So did TL exclusively use his stuff the first game, and then go back to mixing in KF's stuff after that? Not a chance in hell.
Fans and wreckless wording from Leistikow have completely turned this into something it is not
