All the above. No win situation as it is out there unless he comes clean about why.This is what I hate about social media. This coach is going to get dragged before he even knows what's going on.
His options will be to take the high road and continue to be the bad guy, or drag the girl/family through the mud and be the bad guy.
I have no idea what his reasons are. Maybe he replaced her already, maybe she's lost a step, or maybe he has no reason.
