The Wall Street Journal checks in on former HBO creative chief Chris Albrecht, who is trying for a comeback. Last year after a night of heavy drinking in Las Vegas, he was arrested for attacking his girlfriend in a parking lot. He pleaded no contest to the charge and resigned under pressure days later. Now, he's staking much of it on a bizarre, futuristic sport called SlamBall, which failed to break out in an earlier debut. With the feel of a live-action videogame, SlamBall is essentially basketball combined with rugby and trampoline gymnastics, and if Mr. Albrecht is right, it will become a phenomenon as successful and profitable as the latest sports craze, ultimate fighting.
