LeBron James and Kevin Durant exchanged words. Dwyane Wade and Serge Ibaka did a little shoving. Five technical fouls were called, and Russell Westbrook punched a table in frustration. This NBA Finals rematch met expectations. And like that series, it ended with Miami on top. James had 29 points, nine assists and eight rebounds, Wade scored 21, and the Heat survived a frantic finish to beat the Oklahoma City Thunder 103-97 on Tuesday.
