As a Mullen supporter, I'll defend everyone calling for HUD.
They had every right and reason to want a change. I too was very frustrated with game decisions, special teams(still am), defensive effort at times, and all around lack of intensity. Anybody who wasn't probably doesn't care whether we are 10-2 or 3-9. The only difference is I believed after a losing season that we should've given Mullen a year to turn it around. It appears for now that we're headed back in the right direction, but if you don't think we were in a downward spiral then you don't follow football very well, don't give as much of a **** as you think you do, or are blindly following a coach. The biggest thing that has gotten us turned around is play from some underclassmen who weren't quite there yet early in the season, to go with a DC who wasn't quite clicking with his players.
I'll even say this...a 6-6 or worse season next year with a blowout loss to our rival to end the season, to go along with some "quit" episodes where we don't coach or play to the end of the game, and we should absolutely be considering some forced changes at the end of next year; maybe not necessarily at the head coaching spot if we do make a bowl, but coordinators and position coaches for sure.
These past two games were the first times I can think of where we came from behind in the 4th quarter under Mullen to pull out a victory. It's very important too, considering we have a lot of young players on our team that need to believe we can do that. Perhaps a lot of our upperclassmen didn't believe in that, because we'd get stuffed at the goal line vs LSU, Auburn, or let them come back to beat us in the last minute in the past. Maybe even Mullen didn't believe we could do it because he didn't see fight in our guys.
