So, is it confirmed that the 110 is actually going to Miami? Will they be performing at halftime, I would presume?
Yes, I read on the 110's Facebook feed this weekend that they're officially traveling to Oxford for this game. Unsure if they'll play halftime or not. If they made the decision as late as they announced it, it's very likely that Miami already made time commitments to groups/promotions/etc. for halftime (this is commonplace with all schools).
I wouldn't be surprised to see the 110 only playing in the stands and doing a postgame show either on the field or outside of the stadium, but that's just an educated guess on my part.
