Cristobal would have to be certifiably dumb, addicted to cocaine and hookers, and/or blinded by loyalty to his hometeam to leave Oregon for Miami.
His greatest recruiting competition in the PNW just lost to Montana. Wazzu is at suckish levels after losing Leach. Oregon State is historically terrible.
Boise State is the biggest competition.
The PAC12 is bad right now across the board, too. In addition to the aformentioned: Cal, USC, Zona, Az St, and Stanford are also bad. UCLA, Colorado and Utah are middling. He's gonna have Oregon in the playoffs as early as this year. Miami has a long row to hoe.
