I obviously like what I see, but I sense a "me first" mentality from him. The windmill dunks, the post-game interviews, the trying to raise his social profile.
It's all good and the Celtics are the beneficiary of this development but there is a line that can be crossed which can cause some internal dissension on a team when a guy has such a high level of personal aspiration.
I disagree with this on every level.
Jaylen is the dude who tends to defer too much. He often stands in the corner, the ball doesn't swing to him on offense quite often, but never complains.
He is the guy who is more than willing to make the extra pass. Look at the break at the end of the game last night, when Kyrie passed to Jaylen. He touch passed it to set up the alley oop dunk for Jayson Tatum. Now rewind a few plays earlier, when Jayson Tatum stole the ball, and tried to force it in on two guys, when, if he had been more team oriented, he would have been able to drop it back to Jaylen Brown for an easier opportunity. I'm not intending to knock JT, he is a rook, and I like his attack personality. But to say that Jaylen is too focused on his own growth--i.e., that he is selfish--is completely off base.
