Toronto Raptors guard Dennis Schröder was on the Raptors Show on Sportnet and was asked about Saturday's challenge and decided to complain some more.
He says that Joe Mazzulla asking for the challenge when he did (Just a few minutes left in the game. Celtics with a 20+ lead) is the "same thing" as being up 30 and shooting with 10 seconds on the clock. Sorry, but it's not. Players are still expected to play hard with 3 minutes left and up or down however much. Mazzulla sitting on his hands and not coaching at that point would be wrong.
