In a way that’s entirely endearing, Grant Williams sometimes comes across like he’s pretty sure he’s one of the Celtics’ stars.
He chimes in with instructions in the huddle. He nicknames himself Batman, a hilarious semi-serious transgression of ego that turned his teammates into a bunch of jokers at his expense. And when he’s really feeling good, he has no qualms about teeing up 3-pointers like an honorary East Coast Splash Brother.
Among NBA fans who are still learning about the particulars of the Celtics’ second-half transformation this season into an authentic championship contender, Williams probably wouldn’t be one of the first six or seven players they would identify as important to the turnaround.
