MEMPHIS, Tenn. — The Grizzlies are enjoying a day off after wrapping up the franchise’s first berth in the Western Conference finals. Good thing, too, because they can use a little rest after all that hard work.Memphis eliminated defending Western champion Oklahoma City in five games, beating the Thunder 88-84 on the road Wednesday night. The Grizzlies now wait for San Antonio and Golden State to finish the other conference semifinal.Coach Lionel Hollins gave his Grizzlies the day off Thursday because the Western finals won’t start until Sunday at the earliest.“The playoffs are stressful for the players and physically taxing as well as the emotional part,” Hollins said.
