I can only talk for myself.
This is the year I will judge him, All his guys in the program. Senior 4 yr starter at QB (who also happens to be one of the top 5 in the country). More experience and talent on the field than any other program. Per 247, Texas has the 5th most talented team in the country behind only Georgia, Bama, Clemson, and Ohio State.
If Tom can't win the conference this year, he is never going to get it done.
I will only judge him on this one fact, win the conference or you are done as far as I'm concerned.
