As Dwyane Wade shook himself free in overtime, he went up with the shot and the best measure of hope for the Heat. Boston fans stood and held their breath. LeBron James watched from the bench, fouled out. Sometimes for all the talk and sweat and controversy it just comes down to this: A shot going up and running in or flying out. Wade let the would-be winning basketball fly from the 3-point line at the end of Game 4's overtime Sunday night. He had good form. He watched it intently. It hit a couple of inches long, bouncing off the rim high into the air and taking the Heat's chances for a commanding lead in this Eastern Conference Finals.
