Mitchell Robinson told the Globe he'll be OK after tweaking his ankle but was hard on himself about his performance: “I got my ass kicked on the glass. I can’t have no starts like that. It’s cool to get out there and put on that Boston jersey for the first time in a regular-season game, but overall, I still didn’t do what I needed to do. I gotta compete better. I feel like I didn’t compete at a high level that I normally do and I was kind of slow on a lot of things.” #Celtics #Pistons
