After Kevin Durant departed 93 seconds into a 112-108 loss to the Washington Wizards on Feb. 28, the Golden State Warriors displayed a vulnerability that few would have imagined even without their perennial All-Star. Including that setback, the Warriors dropped five of seven games, allowed the San Antonio Spurs to threaten their perch atop the Western Conference, and shifted conversations throughout the league relative to how the remainder of the season would unfold. The Warriors (59-14) claimed their seventh consecutive victory on Sunday night with a 106-94 home win over the Memphis Grizzlies, tightening their grip on the top seed in the West and setting the table for a rigorous four-game stretch of games, a run that starts Tuesday against the Houston Rockets at Toyota Center.
