Well, although a program like Oak Hill already has the reputation, he probably sees a positive benefit from reminding the public whenever possible that the #1 recruit transferred to play for his program. I also wonder how much of a relationship there is; they've only had an off-season together so far, although it's possible that their relationship goes back further. Otherwise, I doubt that HG would be confiding too much inside info to him, given how close to the vest he's played things so far.
Exactly, that is what I was thinking. He seems to be the major "source" of information on his recruitment and he has only known Giles for a few months. Although he probably knows a little more than the average bear, he is probably just as much in the dark about leaders/the front-runner as everyone else.
