Zion had a high level season. Not elite, but borderline all star numbers. 21 ppg on just 13 shots with a YS% of 64.4%. That is 1.62 points per shot. That is uber elite far higher than prime Wilt as a comparison. His 1.6 assist to turnover ratio is solid and that was the lowest it has been in 4 seasons. Not a great rebounder at 5.7 rpg and 10.3 trb%. WS/48 at .159 is very good (better than Tatum, Brown, or White).
So Zion in a down year is an elitely efficient scorer, that doesn't turn it over much, and is a solid passer. He scores almost entirely inside, which is something Boston doesn't have either.
I'd love to acquire Zion. I think he'd be great next to Tatum. I don't think it will happen though as even if Boston was willing to trade Brown to New Orleans, I don't see why New Orleans would trade Zion for Brown. They'd want Brown to play with Zion. Now if we could get Zion for White and draft picks, we should. Then move Brown in a trade for a PG (maybe you get Sengun and Vanvleet or maybe a Murray centered trade with Denver)
