The Cavs broke their losing streak. That's the good news. But that doesn't mean they are no longer considered the worst team in the NBA. It might take a winning streak equal to the losing streak to change that perception (not really, but you know what I'm getting at). So it should be no surprise that they haven't improved their standing in the SB Nation NBA Power Rankings.
The Cavaliers are champions! Long live the Cavs! (Serious question: do they have another 20+ streak in them? Probably not, as they've had the league's toughest schedule so far (meaning more Clippers-y teams are on the way).
The Cavaliers played their hearts out to end that streak, but they came out and layed down a stinker the very next game against the Wizards. So who knows how they are going to play for the rest of the season. But I expect them to come with good effort more often than not, because nobody wants to be labeled as the worst team in the league for too long.
