Josh on USC just said a connection to the program, someone he trusts and he knows said a former coach is reaching out to players to stir the pot against Riley's staff.
Any activities like this would be grounds for legal action. For example,
I can assure you that if Bo tried to undermine the team or 'stir the pot' against Riley, that would be grounds to terminate any further payments to him on his contract as well as a suit for damages etc. You can darn well bet Bo has ZERO goodwill remaining with any of the Administration and or Perlman etc. They would not hesitate to save the budget a few million and embarrass the hell out of Bo if they can. Assistant Coachs who may still be collecting money would also be in similar jeopardy. Alienation, interference with contract, slander, libel, etc. There would be numerous legal actions against anyone that is 'bad mouthing', etc. Trash talking if it is provable is actionable legally. I would think Riley and Company would have legal grounds as well.
