re: Texas A&M made Gus' arse quit in 2014.

I think you're half right, during his post game interview it really seem like something changed in him. It's like he totally wrapped up the season after this loss.

Start about the 2:30 mark... he talks about "having dreams and goals for that season and they just didn't get it done", seems as though he just quit even though we were still in the race.
