It wasn't the Christmas gift Marcus Smart asked for.
Midway through the second quarter of Boston's holiday visit to play the New York Knicks, Smart looked up to find 7-foot-3 big man Kristaps Porzingis sprinting down the lane at him. Considering Porzingis' penchant for poster dunks early in his NBA career, Smart could have been forgiven if he elected to simply step out of the way. But that's not in Smart's basketball DNA, so instead he cemented his feet in front of the charge circle and braced for the inevitable collision.
Porzingis tried to dump the ball off at the last second, but still plowed hard into Smart, who toppled backward and earned the charge call for his trouble.
