The Memphis Grizzlies appear to be playing hardball with Tyreke Evans. The veteran forward has drawn interest from several teams — including the Boston Celtics — ahead of Thursday’s 3 p.m. ET NBA trade deadline. But according to ESPN’s Adrian Wojnarowski, Memphis has a hard-and-fast asking price for Evans that other clubs have yet to accept. The Celtics, Denver Nuggets and Philadelphia 76ers currently are the three “frontrunners” for Evans, according to Wojnarowski’s Tuesday report.
