I am just going to make some educated guesses. First, he had to adjust a bit and develop some relationships in the SE. I would have to look it up, but it seemed like a majority of his recruits at Texas were from Texas, Canada, Nevada. Of course, he had the occasional one like KD from DC.
Second, I can’t remember him publicly speaking on it or not, but I recall him souring at 5 stars who thought they were one and done at Texas, but they really weren’t. He seemed to adjust to that starting at UT by recruiting guys who weren’t 5 stars but would take tough coaching. I think you can still make this argument with the 5 stars- all seem to want to get coached and come from great backgrounds. Just read what they are already saying about Keon’s work ethic, and locally in Memphis, the reports are that KC has really worked hard to get where he is. It hasn’t all been athletic ability.
These are just two things why you may have seen a “slow start” in recruiting at UT. But I said at the time that I was definitely on board with his hiring because he brought instant credibility to a program that was in terrible shape.
