I know, I know, it's ridiculous to pay attention to stuff like this, but I will say it has helped me tremendously in the last two hiring cycles! Read at your own risk. Here are the places I think Trev has visited so far based on my investigative skills.
Stoops at Kentucky
Leipold at Kansas
Whittingham at Utah
Nashville- I am not sure who that could be.
Des Moines- Campbell, perhaps? (Trev also grew up not too far away from there, fwiw)
Note- it is possible (actually likely) some candidates could meet with him away from their current location, which has happened in the past with previous "recruiting" trips like this. He may also have talked to folks in Lincoln who were there covering the game (wink wink)
We need some "lighter" material in here lately, just some food for thought, my disclaimer is that I am not always right (but I'm right a lot)
