By the time Kevin Durant celebrated his first NBA title and clutched his first Finals MVP trophy last June, a knee sprain that had nearly ended his season prematurely was already an afterthought. The Warriors' near-invincibility throughout a 16-1 jaunt through the playoffs had all but erased the vulnerability and anxiety that accompanied Zaza Pachulia's awkward fall onto Durant's leg in late-February. Golden State lost one of its MVPs, Stephen Curry, to a friendly-fire knee injury on Friday, a grade-2 MCL sprain that will reportedly sideline him for at least three weeks.
