With a ball in his hands, Earl Boykins is one of the fastest players in the NBA. Put him in skates, and he might as well be frozen in time. "I can't even roller skate," he admits. With a stick in his hands, Joe Sakic is one of the most prolific scorers in the NHL. Give him a basketball, and he might as well be holding an anvil. "I don't have any touch," he says. "I can't even stand there by myself at the foul line and hit one."
