Remember when the Heat were supposed to challenge the Bulls' single-season wins record? We're not saying it'll never happen, but we are saying that it won't happen this season. The Heat have lost four of their past five games, and things are starting to look grim in Miami. In Saturday night's loss to the Dallas Mavericks, LeBron James added Erik Spoelstra to the short list of coaches he's bumped ("bumped" here meaning "kind of hit with his shoulder as he walked past in what is usually considered a disrespectful manner"). That's just the latest in a series of signs that Spoelstra might not be a long-tenured fixture on the Heat's bench, but is he really the problem?
