https://Str8bet.net is mentioned there above. So yeah it does look like he's involved with it. The site appears to be one of those agent-banked sportsbooks, where the agent pays for the constant updated odds and the system taking/grading the bets, and then the agent is responsible for all of the money handling.

So if Mike was an agent for this thing, and can't pay, the above would be a possible result.
