After thinking and reading a bunch of responses the last few hours. I'm convinced (although unfounded) that the timing of the firing of SE is completely due to Scott Frost having a great start, and becoming the next hot name for a P5 offer.
Bounds/Green probably went up to SE and said "look, here's the deal, you are going to contact UCF and Frost...and give him this offer."
Shawn said No and so they canned him. They hire Moos and in the interview said the exact same thing. You want this job, you're going to go get Scott Frost for us. He said "ok, easy enough" and now here we are waiting for 5 weeks till the announcement of MR being fired, and another month+ for the announcement that Frost is our guy (if UCF gets to a new years six bowl)
There's literally no one else. This was the plan from the get go, because the window is getting small on Frost. Had to go get him this year, even if they wanted to wait for another year.
