I had mention those possibilities in my post above along with cash considerations. Here are the details on Uconn taking Houston's away game at Vandy.
" Connecticut will replace the Cougars on Vanderbilt’s schedule — the game will also take place on Oct. 2, according to a copy of the contract obtained by Vandy247 from the University of Connecticut via open records laws. The game will not be part of a series and is instead a one-off matchup. But according to the contract, Vanderbilt will not pay UConn to come to Nashville. Opponents for nonconference "buy games" typically receive substantial payments that sometimes exceed $1 million. The contract was signed on July 14 and the buyout for the game will be $1 million. "
If Houston is the move sounds like one of those you keep the cash and play us instead that DB has made with other
schools. Don't know what Houston was to be paid to go to Vandy, but it had to be an easy sell to Vandy ( possibly splitting/taking over all costs) since it looks like they draw worse than Uconn.
