I don't think anyone can credibly defend Butch anymore. The better question is what is best for the program now? Is a new coach the answer (and if so who?) or is another year of Butch necessary for stability and financial reasons? Again, I don't know how you can intelligently argue that Butch will win championships at UT.
What potential coach out there would be an improvement? Would you take Les Miles?
I wouldn't take Miles, but I am now on the Fire Butch Jones bandwagon for the first time. Do it now and get the inevitable over with. We know it's going to happen eventually anyway.
