Mark my words, Brown is gone after this year. I don't know who will take over for him, but Brown is gone. They play awful team defense, even though they have great potential with their length. They do a horrible job keeping the ball on one side of the floor or funneling things to the sideline. They don't closeout well or make the other team take bad shots.
Their offense looks ok, especially considering the lack of shooting other than Reddick. I still seriously question the decision to make Simmons a point guard. Hopefully they eventually get another ball-handler so Simmons can be a roll-man.
I'm just not scarred of them as a Celtics fan. When it comes down to it, I don't think they can score consistently on a good defensive scheme unless Reddick and Covington are out-of-their-minds-on-fire.
