FWIW, Dixon played at TCU, so he could have a very strong connection.
According to one Pitt site TCU is saying they are willing to double Dixon's salary, which depending upon whether you mean the 'base' or the 'total compensation' is 2 very different things, and his $10MM buyout. So TCU is certainly willing to spend the dough. Note they are 8-60 since joining the Big12.
FWIW, GT has reached out to Tyson Jolly (the SG DTM tweeted from the previous page of asking out of his LOI from Cal). He is from OK, playing prep ball in FL. In a Scout article he mentions he might want to be closer to home so it sounds like someone in the Big 12 is most likely to end up with him.
