SBN/Notre Dame bizjet traffic

There is a ton of bizjets inbound to SBN for presumably the ND vs. BC game. Probably 25+ jets alone, including a fan charter (?) ATA 752. I know ND has an incredibly strong following, but do any other universities see this kind of draw?

Looks like two 757’s:
AMT6436 (the one you mentioned)
NWA9981
