I don't think Ball will look good running with Smart and Okafor. He needs like KO/Horford type bigs, wing players that are not gun shy but accurate like Jae Crowder or Bradley, IT4 can run with Ball too. So I agree, it will be a good decision to draft Ball but it will entirely depend if Stevens "sees it" with him, meaning the offensive schemes become more effective with Ball and his playing style brings out the best in guys like Jaylen Brown, Marcus Smart, etc. I mean, just look at how many shots UCLA gets up every game! It's 5 star dishes, different exotic fishes levels of ridiculous.
When it comes to the trades though, I have a feeling that it's important to note that Ainge has been on a fleecing tear (Nets picks, Crowder, IT4, etc.) So teams around the league want him to be had on one of these future deals, I'm sure they think he's been penny-pinching them for far too long. While some of these scenarios work in theory, you can't expect those teams to accept marginal picks and raw players for a prospect like Okafor, who while antiquated should still be able to get you two points here and there at will. Especially if Ainge is the one making the offer, they probably had enough of him winning all these trades.
