FOR DEFENSE TO BECOME A PRIORITY? Ready...Kevin Durant went from special as a 19-year-old rookie to spectacular as a 20-year-old sophomore. Now, as a 21-year-old entering his third NBA season, Durant has gotten wiser, stronger and more polished. In his second season, he improved on all of his weaknesses and could be ready to go a step further in Year Three. He’s shown a newfound commitment to defense and a do-whatever-it-takes attitude when it comes to avoiding a repeat of last season’s 23 wins. ...Or not: Durant’s playmaking has yet to develop to the point where he’s making others around him better. He averaged more turnovers than assists in both his first two seasons and nearly led the league in offensive fouls committed last season with 39. Until he proves otherwise, Durant’s biggest question mark will continue to be his defense. The Thunder gave up 8.2 points more per 40 minutes with Durant on the court in 2008-09. And before he becomes a superstar, Durant must consistently take over games down the stretch, and not just with his scoring.
