“I think Mitch is involved with Maryland,” Jefferson said, referring to one of the six schools on McGary’s list. “And I have had Maryland say, ‘Tell him that I said hi’ or something like that. And they will give him a call and Mitch will be like, ‘What’s up [to Jefferson]?’
That's pretty cool that we were the school specifically mentioned; no idea what it means in the end, but I think it's a minor positive.
