UM gets an assists with their sign stealing program, so that washes out. Believe it or not, UGA peaking at 39th out of 130+ teams is not that bad.
As such, I wonder if that research article did a deep dive as to what kinda penalties that either took points off the board or put points on the board for other teams. I would wager those championship teams didn't have that happen as much. Also, championship teams are going to have 2 team & third team playing time. Those 2nd or lower make goofy plays all the time but they are in clean up duty.
Lastly, theres a difference between intensity penalties Vs complete dumbass penalties. I don't stress over facemask/personal foul penalties by DB's. But false starts, offsides, losing tempers, etc.... that's far different. Championship teams play fast & furious where they are going to get some of those penalties but bonehead personal foul BS or false starts, not so much.
What we are seeing w/ CKD is mental weakness, not mental toughness. And if a team isn't mentally tough there is NO WAY they will all the sudden be physically tough. They will wilt every damn time & start doing stupid shit or getting mad or puffed up & need their safe space stuffed animal.
