I was listening to it on the radio, the BOOS were very audible. It surely wasn't because the guy slammed the ball or tried to show up anyone. LA people do not boo for that stuff, they don't care enough to boo. The arena was half empty until about halftime last night according to the local guys, so they don't even care enough to get to the game on time.
As for Mussberger, who knows what he meant, if he commented on it, you can bet (no pun intended) it was gambling related. When he does football it is painfully obvious, he lives and dies on every play like any other degenerate, probably what makes him a good commentator, he has a VESTED interest in the game. Same as with Al Michaels. Prnbably why Joe Buck and that other clown that works with him suck out loud, they probably don't even know what a line is, unless it is made of chalk, or on a mirror.
Sports arethese guys lives, and they THINK they know more than even we do, so why is it so hard to believe they don't gamble? You don't think Al Michales thinks he doesn't know football better than Joe Public? Of course he does.
