8 is probably safe for TH. Tulsa, ISU, KU, KState, and Baylor should all be wins simply on the significant talent edge. Tech is just above those teams, but UT should have the edge there too. That's 6 wins. OSU is the next step up, but UT hasn't actually beaten OSU in while, even when you should have. Then there is USC (equivalently talented as UT), TCU (better coached thus far), WVU (stud QB and system) and OU (the Big12's best until proven otherwise). To get to 8, you have to win all the "winnables" plus one of the last 4. If I had to predict, I'd say 7 wins, but if he gets to 8 then he's won at least one game he's not favored in and should be safe. Real question is what's the floor before the seat gets real warm for 2019? If he loses the last 5 on my list (OSU, USC, OU, WVU, & TCU) and ends the season 6-6, what will your thoughts be on TH? This to me is a realistic possibility, and would lead to the "fire an assistant coach as the scapegoat move" all hot seat coaches do.
