The Boston Celtics traded haymakers with one of the league's best on a national stage Sunday and nearly stole a win despite playing without their All-Star point guard. From this vantage point, there was a lot to be encouraged by, not the least of which was 21-year-old Jayson Tatum being the best player on the floor in a game in which LeBron James was on the other sideline. Most of the venom was directed at the officials - more on that in a bit - but poor Brad Wanamaker and his bench brethren found themselves in the crosshairs of angry fans, too.
