Betting on your own team doesn't make it okay. It's forbidden for a reason. Players can easily manipulate the line by betting on their own team. If bookies got word that a player like Rose bet less than his usual amount on a given day, they'd assume something is wrong with his team, and they'd move the line accordingly (and vice versa). The outlaw line would eventually make its way to Vegas. Then the player could send a beard into a Vegas casino and make a huge bet after the line's been moved. Rose is a scumbag, and he's now admitted it. Keep him out of the Hall, and preserve some kind of integrity in the game.
