I don't know, my sister and her husband, as well as my dad and several of his friends, are Gators, and they all love Meyer still and many have even started following Ohio State a bit (still Gators No. 1 to them, though) since he became the coach there. From their perspective - and I didn't pay enough attention at the time to know how true this is - Meyer actually did a good thing by coming back for one more year when he had the health scare, because leaving so suddenly would have had a horrible effect on the team. Hardly a scientific survey, I'll grant you, but there it is.
In any case, even if it's not true about Meyer, if what Meyer did was burn bridges in Gainesville, then Petrino leaves scorched earth behind him wherever he goes.
