BOSTON -- Celtics fans taunted Philadelphia 76ers forward Ben Simmons with a "not a rookie" chant in the second half of Monday night's Game 1 of an Eastern Conference semifinal series at TD Garden, then came back with a "he's a rookie" chant while Boston's Jayson Tatum was at the charity stripe later in the game.
Tatum, the No. 3 pick in the 2017 draft, scored a postseason career-high 28 points over 40 minutes as the injury-ravaged Celtics emerged with a 117-101 triumph. Tatum joined Larry Bird as the only Celtics rookies over the last 50 postseasons with 25 or more points in a playoff game.
