Okay, this whole thing seems mysterious to me.
1) Greg couldn't dig up anything. To me, this means it's all being kept very quiet @ USF.
2) Let's assume Schad's tweet is correct, and who 2000bull saw was indeed Dyer. Then, yes, he did visit.
3) He took a visit, which means both parties were seriously interested on paper prior to the meeting.
Possibilities:
A) It went well for both sides. This means Dyer could be here very soon.
B )It went badly. We will never hear anything from the USF side.
My guess is that if Dyer is coming to USF, we will hear something by this weekend.
I give this an 82% chance of him coming to USF.
Why? If USF had a problem at all, either from CWT or his bosses, there would not have been a visit.
Wildcards:
1) something snags in the admissions paperwork, such as a course doesn't transfer, etc. [i don't know! pure speculation]
2) another school steps in and Dyer sees a better deal elsewhere.
3) after the visit, USF talked it over and decided that it's too risky.
4) after the visit, Dyer doesn't want to put with the USF requirements.
