Jaylen had Smart, Rozier and Morris all angry with him against N.O. and deservedly so. Everyone seemingly buying into their roles and making the right play consistently except for Brown. He is forcing things and playing selfishly and that don't sit well especially with Smart. Jaylen needs to put his supposed intelligence to work on the basketball floor, as of right now he is displaying far and away the lowest BBIQ on the team.
That's kinda the trouble with these kids overachieving last season. They went further than they had any reasonable right to go. Bucks were coached terribly and we got by them. Philly was more talented, but they celebrated their Round 1 victory like it was the culmination of the process and came into the series against us emotionally drained and completely unprepared - we kicked them in the teeth. We gave the Cavs a good fight in the conference Finals until LeBron closed it out.
I think the biggest adjustment was Rozier and Brown. Those two thinking they were world beaters and now they are being asked to sit down and know their roles. It's less of an issue with Tatum, because Tatum's role all season was smaller than it should have been - we knew he'd get more touches this year. It's the other kids that have struggled to adapt to the "new reality".
You know, when Boston formed the late 00s Big 3 of Pierce, Ray and KG, there had been concern that having too many alphas might cause problems. The rebuttal to that was that all three of those guys had already spent years as "the man" and got it out of their system. They were in their 30s now and ready to just sacrifice individual stats for the greater good... That's a harder sell for a 22 year old like Jaylen Brown who has visions of himself making all-star teams, getting shoe contracts, and being a personality that stretches beyond basketball. I'm not sure if he's going to be able to just accept being 6th man long-term here. It could be a problem.
