I think Jaylen Brown is an awesome #2 on a championship team and he proved that in 2024. That's perfectly fine IMO. I will say though early on this season, he has made some good plays and facilitated but guys like PP, White (early on), etc. are bricking open looks. He could easily have a lot more assists each game and our record could probably be above .500.
The turnovers and dribbling issues will probably always exist and prevent him from being an alpha like Tatum. But I can't really criticize him for the first five games this season, he's mostly been excellent. Jaylen can rebound but he's not really known for it nor expected to and our frontcourt has mostly been abysmal too leading to second chance points and ORebs for other teams.
I still think Jaylen is a Top-15 NBA player in the league if you also factor in defense. Frankly if you did a deep dive on some of the guys in the 10-20 range ahead of him you can easily nitpick stuff on them too and I think a few of them are overrated
JB is a terrific basketball player. Obviously imperfect, but very glad he's here. His midrange game is beautiful. Been knocking down threes this year and I don't feel that he's over-shooting it. He is what he is with the ball. Sometimes gliding gracefully to the hoop; sometimes looking like a keystone cop. But again, so glad he is a Celtic.
