I may be thinking outside the box but ...
The mobsters, or whoever controls the gambling could possibly use this to make a lot of money off of getting players removed from teams and changing the outcome of seasons or possibly even a Super Bowl.
I am sure there are a lot of gold digging people that would take a large sum of money to press charges and then disappear into the night.
I am NOT saying that is what happened here, just saying that it could easily happen, with they way some of these players like to party.
