I would guess the MVP level ($10,000) and up should be good enough, and probably down to the Director level ($5,000). With 4 schools, sponsors, ticket agencies, general public, etc., the university will likely only have 2,000 tickets at most. All of the big donors will be there, gobbling up as many seats as they can. This will probably take care of 1/2 of those tickets, if not more. Since this is in the north east, there will be lots of other boosters (that includes all alumni) looking for tickets as well. If you're not a preferred seat holder or Assistant Coach level ($1,500) donor I doubt you'll even get a whiff of the university's ticket allotment.
I suspect you may have better luck through the other 3 schools at the regional or via secondary markets.
