Like thousands of you, Doctor S has been asking, "What the heck happened to SlamBall?" A quick Web search turned up the disturbing news that Spike TV has dropped SlamBall so that it can show three more episodes of "Star Trek" every Saturday night. But SlamBall officials vow that season 3 of every hyperactive person's favorite sports will return to the tube soon and the league will go on. What really needs to happen is the creation of a real Rollerball league. But not to the death, of course. Except during the playoffs.
