...The only people who are clearly in the wrong here are those that think that it doesn't take significant practice time to have it as a workable alternative. The three fumbles in the scrimmage show what can go wrong if you don't practice it enough.
I rarely resort to quoting myself, but I will do so here. The only people that are clearly wrong are those that think that they can just add under center plays without devoting significant practice time to perfecting snaps directly to the QB. They make the erroneous assumption that "everyone knows how to do that". I believe Pruehs was cited as saying he had never done one since 9th or 10th grade, and for Maxwell it was the same.
Let's guess that they spent 10% of their practice time in the Spring working on this. That's time they couldn't spend working on something else. Whatever time they spent was clearly not enough, because when they tried to actually use the formation in the scrimmage, they repeatedly fumbled the snaps. Thus, this Fall they will have to either abandon it, or put more time into working on this. I have no idea whether they will consider the direct snaps to have been a failed experiment, or whether they will continue to work on them in the Fall. I certainly hope they won't try to use it in games unless they can use it without a high risk of fumbling.
Again, BTC argued that the main reason why most college teams never go under center is that it takes significant practice time to get it right. I was skeptical at the time, but Spring practice has proven him to be correct.
