Dayton is great from a philosophical fit. Similar school in terms of religion, they invest in basketball, fervent fanbase, they may not be a major market, but DePaul has a major market and they suck.
I think Dayton is a great fit as a 12th team. Absolutely ideal in that they mesh well with the rest of the league and currently are performing at a high level. But I wouldn't bring Dayton in just for Dayton. If we did add UConn or VCU, I would say get Dayton as #12. If we found that ideal East Coast school that was a must-add, Dayton would be a great choice to be the Midwest school to balance that out. But bringing them in just because they're Dayton? That's not good enough for me.
