Celtics coach Joe Mazzulla responds to Dennis Schroder’s ire over late challenge in Raps’ drubbing

“Up 30 you’re not supposed to challenge nothing.” said former Boston guard Dennis Schroder of Mazzulla’s late call dispute.

When Boston Celtics head coach Joe Mazzulla challenged an out-of-bounds call on a play late in the Celtics’ 117-94 drubbing of the Toronto Raptors at TD Garden on Saturday night, it rubbed some of the Raptors the wrong way.

Given the contest was part of the group play segment of the NBA’s new in-season tournament where point differentials impact a club’s ability to advance, it might have added some extra impetus for the Raps’ players being extra salty about Boston’s evident desire to leverage every opportunity available to them in the contest. But former Celtics point guard Dennis Schroder in particular had some sharp words for the situation postgame.

“Up 30 you’re not supposed to challenge nothing. You won, it’s three minutes left. You shouldn’t disrespect us like that,” said the German floor general to the Boston Globe’s Gary Washburn.
