Last season, Marcus Morris knocked down a game-winning 3 against Paul George and the Oklahoma City Thunder. A game-winning shot is always a big deal, but this one had a little more meaning for the Boston Celtics big man.

“I’m gonna take you back to a little story why that meant a lot to me,” Marcus Morris told A. Sherrod Blakely of NBC Sports Boston. “Two years ago, I was in Detroit, and Paul George did a commercial. I never told anybody this. In the game, it was a Gatorade commercial, and he was counting down, ‘5-4-3 …’ in that commercial they had a person that looked exactly like me. And I noticed it because I was like, ‘Wait, it’s a Detroit Pistons jersey on.’

“They blanked my number out but it was the exact form of my body. And everybody I told watch was like, ‘Oh.’ And when I had seen that, I thought that was just so disrespectful.”

It's not exactly Paul George's fault that Gatorade based the defender off of Marcus Morris, but George was just caught in the crossfire. It's an odd grudge for Morris to hold onto, but it motivated him to knock down the big shot.

Hilariously enough, Morris also hit the game-winning shot to beat the Thunder on Thursday night. This one wasn't at the buzzer, but his 3-pointer with just under 30 seconds to play gave the Celtics a three-point lead. He then knocked down another free throw shortly after for good measure in a 101-95 come-from-behind victory.

Marcus Morris is off to a hot start for the Celtics, scoring 13.0 points per game on 48 percent shooting. He's also hauling in seven rebounds per game, and his presence off the bench is key for Boston's success this season.
