Problem with his coach according to WHO-TV report last night is that he is a con man. He takes money to coach and house these poor kids, but doesn't pay the bills. He wrote a bad check to a church in DM for a van, and hasn't paid bills for his or the kids housing. The kids are actually going to get booted from their apartments 'cause no-one's paid rent.
WHO talked to a kid's mom in DM who dipped into her 401k to pay the guy $600 for 10 coaching sessions, and Alexander disappeared after the first one.
If any credentials are needed for his time at this "prep school", there might be a lot of red flags.
Ain't no place for con men in amateur basketball.
