First, I wonder if the league can even do anything without proof that it is actually Sterling speaking non the recording. Second, WHAT exactly can they do? There's probably some text in the bylaws of owning a team about conduct, but I'm sure they can't take a team away or force them to sell. Because if a guy is actually prosecuted for being a bigot, and the league didn't do anything then, I suspect the punishment will be a hand slap. Most likely, you'd be looking at draft picks being taken or something like that.
