Of the 5 longest NBA winning streaks since 2000–the Rockets of 2007-08, the Celtics of 2008-09, and the Suns and the Mavs of 2006-07–only the current Miami Heat still have a chance of winning a championship the same season. And if there’s a reason for this wishful thinking, might the streak be taxing the Heat a little bit both physically and emotionally? I mean, probably not LeBron. He appears to never tire. But the other guys might be thinking they’d like some mental and physical rest as the season winds down. At the least, if the Heat do lose in the playoffs, you are likely going to hear ‘the streak’ as a leading explanation.
