In a pickup game, Olynyk gets picked before Morris, but assuming Wyc isn't completely indifferent to paying luxury tax, I'd rather have Morris for 2/11 than KO for 4/48.
So we added Hayward and swapped KO for Morris, and all it cost us was a year of AB. The people who are complaining about this just don't understand the business side of the game.
I do wonder if some of the hysteria is really continuing angst about the Fultz/Tatum deal. If you don't like that deal (and I'm one of the ones who doesn't), it casts a pall over the entire offseason. But that deal has no significant impact on Danny's other moves, so you ought to be able to judge those other moves separately on their merits.
I'd take KO on his contract over Morris on his. Olynyk is a substantially better player who still has potential for improvement. But, I'm firmly in the Olynyk is a good (as in, clearly above average) NBA player camp. Of course, that was never an option. I'd much rather have Hayward on his contract than KO on his and I think I prefer Morris to Bradley given contract and roster fit.
But, that roster fit is because we had to jettison Olynyk and Amir (he was much better than some acknowledge during the regular season but obviously was a shell of himself in the playoffs and might be approaching the end). Morris is worse than either of them were last year and it's not close. On the other hand, Morris does have more defensive versatility as he is more capable of switching onto true wings than either was. This may carry some marginal roster benefit, especially since the Celtics play a switch heavy defensive scheme.
I'm torn overall on Bradley. He has serious flaws in that he's not much of a passer and cannot create his own shot. He's also short. But, he's a good shooter, turned himself into a good rebounder last year, and plays elite man defense in flashes. At the end of the day, I'm not convinced he's actually a great defender though, largely because the modern game demands the ability to switch and he is too short to effectively defend a lot of the guys he ends up guarding. I also think his elite level defense demands so much energy that he cannot sustain it throughout games, even in the playoffs. So, he's not really an elite defender, despite his reputation and the flashes. I think Bradley was the most overrated player on last year's team and the guy the team will be least impacted by losing.
