Ross Dellenger never said that UConn to the Big 12 was inevitable. He barely discussed UConn to the Big 12.
Mark Zanetto, who is not a good interviewer, is the one who brought up realignment and UConn. Zanetto said (16:52):
"Um, but as far as like realignment and media rights,
there's it's it's an interesting one because, you know, if UConn is still considering a move to a P4 like the ACC or the Big 12, are they now more kind of waiting on media rights timelines to kind of dissipate or end?"
This is piss-poor for Zanetto to say that. If UConn is still considering a move to a P4 like the ACC or the Big 12? Give me a break. If UConn is still considering a move? This implies that 1) a move is in UConn's control and 2) they possibly aren't considering a move. Ridiculous. Neither is true.
As far as what Ross Dellenger said, he said that 1) a breakaway of basketball and football was inevitable and 2) never say never to expansion happening (not specifically UConn) before the media contracts are up.
