Jaylen is overpaid. However, that doesn't mean he stinks. His game is transition. If you give him the ball and he has a half step on his defender - doesn't matter who that defender is - it's 2 points. If he pulls up for a 3 in transition, even if he has a teammate open, I'm good with it, because he converts a LOT of those. I like when he's selfish on the break. In those situations he's right up there with the best in the league when it comes to finishing.
He defends, he rebounds. His passing, while not great, I'd say is good by NBA standards.
The struggle comes in the half court offense, which is why last night's game may have been significant. When opposing teams put a guy in his grille and try to get him to advance the ball by dribbling, he'll cough it up. Especially going to his left. And he doesn't always make the best decisions when they're working the ball around trying to get a decent shot opportunity.
So in that regard, last night's game was interesting and his improvement - if there is any - bears watching. But Milwaukee is also not a great defensive team. They had serious problems guarding us till the 3's stopped falling in the 2nd half.
He does work well with Porzingis - the end of the Charlotte game excepted. So his development, I'd say is one of the main storylines to follow with this team as the season progresses.
