Since Auburn will obviously have to get off their buses at some point, and one would expect Auburn fans to be there to greet them, what exactly was requested that Tennessee officials don't want to allow? Was it a matter of Auburn wanting to get off the buses some distance away (doubtful, I would think) or maybe it was the "event" aspect, and UT asked that the Auburn band not participate?
I've never had the opportunity to see the visiting team arrive (at least not in the last 20 years or so), how does that work? Do they let them out on Stadium, err Fulmer Drive and they walk down the hill, or do they ride the buses down the hill and then get out? I see their buses parked on the hill on Tee Martin Drive (the alley that runs down the hill and under the stadium), but they are backed in, which I've always assumed happened after the team dismounted.
There is not a lot of room in that area, and with so many fans trying to get to the gate 10 ramp, could be UT is concerned about too much congestion.
And, in Auburn's defense, (can't speak for Oxford) I remember seeing the Tiger Walk long before Tennessee started doing it.
