Couple of things.
Herman's coaching. Spectacular when focused, look no further than the 6-0 record vs top 25 teams and 3-0 record vs top 5 teams. When not, SMU and UCONN debacles. Of course the lack of focus at UH was talks about him taking another job (USCe last year, UT this year).
Defense, see above, when focused UH has played spectacular defense, Orlando is fantastic as a DC. He is near the top of my list for next coach....but he has some red flags, very limited exposure in Texas, very limited resume (coached at UH, Utah State, UConn) I'd ONLY hire him if he had a really good OC and a bunch of real quality assistants lined up. The money will be there for that.
Granted it is a somewhat arbitrary #, but UH has only allowed more than 40s twice under Orlando/Herman (both times this season, both times on the road). Bad games happen, Bama has allowed 40 or more 3 times in the last 2 seasons. Some of the game plans Orlando came up with (Navy last year, FSU Last year in particular) were just genius.
Back to Herman. While he obviously wont be dealing with coaching speculation (unless the NFL or Ohio State come calling), while at UH he performed best when UH was the underdog, he was fantastic at getting the kids to buy into the "us against the world" and disrespected aspect, he aint gonna have many games at UT to use that tactic.
He is also over the top demanding and pushes and pushes the kids extremely hard, full pad, hard hitting practice, 110% in everything everyday every hour. This directly lead to the Navy and SMU losses, as the team was beat to hell and several of the injuries were practice related. Obviously UT will be much deeper with talented players, but he doesn't seem to know when to let up. He is like a jockey going to the whip from gate to the finish line.
I questioned last year, if at some point it was going to be an issue with the kids, physically and mentally. I think for a couple 3 years it can work, but in the long run he is going to have to adjust. Which he likely will, he is a really smart guy.
As for offense, he can be extremely stubborn. The Uconn loss, while partly injuries and partly coaching speculation, was mainly lost because of his ridiculous notion to keep running the ball up the middle. The one and only strength of that team was their DLine (3 potential NFLers) yet we just kept running inside over and over. he admitted later that it was a mistake, yet we kept doing it this year, with worse RBs and a much worse OL.
The last redflag on Tom is he is just childishly thin skinned, it is his biggest flaw. His battles with the media here are well documented, and while some of our fans cheered it on (myself included in some circumstances) it was just immature and dumb. He simply can't continue to act like that at a school like UT where the media spotlight is going to be 10 fold.
