Fans that don't pay attention to anything outside of Miami di**riding every coach that has a modicum of success, despite the evidence pointing to said coach being mediocre as ****. It's a Miami fan tradition unlike any other. Key is what he is, a decent coach that has a penchant for upsets. You look at the last two years against Miami, GT didn't reinvent the wheel, he lucked out last year from Mario having a brain fart(and TVD giving them multiple INTs), and this year, Miami being unable to set the edge.
GT is what they've been for most of the last 50 years, a barely bowl eligible team with the occasional big year, when they hit on a concept. He hasn't elevated that program on the recruiting trail, he is a steak and potatoes coach. It's nice, when you have limited expectations(Which GT has, they aren't truly committed to being a world class program), but it doesn't work at programs with title aspirations.
