I don't think it's a coincidence that when Trev was describing attributes he admired, it mirrored Campbell. MC would bring vision, leadership, development. Both Trev and MC take their faith very seriously too, not that it matters, but it does speak too likemindedness. All this to say I think TA makes a hard push for MC, no idea if he lands him or not.
Oh and a pet peeve of mine is MC/Mike Riley comparison. It's just lazy. Saban, Franklin, Harbaugh were all .600 coaches at places with less resources too...
