I saw an article that said he (TaSwawn Thomas) had been unhappy about something and had nearly transferred before the prior coach left.
I'll give you what I know and think (opinion) regarding the Houston basketball situation. There were things "going on" in the athletic department that still haven't been disclosed. For example, there is more to the story why James Dickey suddenly resigned as Houston's head coach for personal reasons, and then took an assistant's job at OSU......
Go back to a little over a year ago. Houston's leading scorer was Joseph Young. Son of former "phi slamma jamma" member Michael Young who was a 1st round NBA draft pick in the Olajawan/Drexler days in the 80's. Joseph was Houston's leading scorer as a sophomore at 18 ppg.
Joseph originally signed a LOI out of HS to play for Providence but Dickey then signed Joseph's dad, Michael, to become the Director of Basketball Operations. Joseph then appealed to the NCAA and ended up signing with Houston ...... even after Providence wouldn't release him.
Some political "stuff" started and Dickey (maybe above him) reassigned Michael Young to some BS community relations job after Joseph's sophomore season .... for as long as Joseph was on the U of H team. Michael didn't take the reassignment well and sued the university. In the meantime, Joseph transferred to Oregon and won his waiver appeal to play for the Ducks without sitting out a year.... I guess to keep Joseph out of the middle of the legal battles between his dad and the university. He then led Oregon in scoring last year at 18.9 ppg as a junior.... I was a little surprised TaShawn didn't follow Joseph to Oregon.
TaShawn and Joseph Young are buddies ..... and the team thought Michael Young got screwed over. Joseph suddenly left the team after his dad was reassigned (fired), but there were still some unhappy campers in the locker room last season..... partly because they had empathy for Joseph (teammate) and partly because the players liked their advocate, Michael Young. After the season, Dickey resigned .... or was forced out. There was still unrest, and then Kelvin was hired.
Players were already unhappy for a year after Michael got reassigned, but then Houston hired a hard-ass coach (Kelvin) who brought a history of NCAA infractions with him. Thomas had enough of all the shenanigans, and decided to transfer. If he had enough time, he probably would have done it the year before.
JMHO on how things transpired at U of H....... I still don't think the whole story has been made public and doubt it ever will.
