I think they will offer 4.7. He will get a higher offer somewhere else. There is a very slim chance he will stay but that would only be because he sees himself in a significant role in the rotation. Much more likely he takes a bigger offer and a bigger role on a lesser team. I really doubt he will be traded. The present contract restrictions mitigate against it.
It is what it is.
I think he leaves for greener pastures this offseason. But a team looking to cut salary might have interest in taking a one year rental that can also help them make the playoffs. IOW, Boston and Dennis. Is it good for us? I have no idea. It depends on several things, one of which has to do with whether we think we can find regular PT for Jalen the rest of this season. With CamJ, Jae, Mcgee, Ayton and Biyombo that might be difficult.
I know that Schroeder can play but I've never been one of his fans. However, despite what's been said here about him lately by several posters, I had thought he'd been somewhat rehabilitated and had moved beyond the selfish, often brain-dead player he had been. If CP believes in him (and I stress the "if") then adding another scoring threat might makes sense.
