I would go neutral maybe wear a gators hat. If your gonna be that guy you might as well go all out and paint your whole body orange and blue take a live gator in the stadium and be as obnoxious as possible.
I went low key with the Gators shorts and a neutral hat. No one tried to kick my ass in front of my family so all in all not bad. Btw if we can't run on those guys , something is definitely wrong because indiana St had way too much success on the ground against the vols.
