SIAP
But according to a thread on a UGA board, there's a rumor that Gattis slept with the mother of a recruit named Xavier Worthy (who apparently found out and flipped from Michigan to Texas). Some people are also saying that some at TTUN are claiming that the reason why Gattis went to Miami was because he was "pushed out" and encouraged to leave because of these allegations.
I didn't pay it much mind (why would this rumor be leaked on a UGA board?), until I saw that a TTUN reported addressed it in a Tweet:
Based on what little I know about this whole Gattis-TTUN situation, I'd guess that some of the things that he said about the culture on the way out was a bad look for the program, so they countered with this rumor to try to save face. There could be some truth to the Gattis sleeping with the recruit's mother (I've heard rumors of happening quite a bit, especially in the S-E-C! S-E-C!), but I don't think TTUN would've had a problem with it if he didn't decide to bail on their shitty culture and program.
