Mitchell doesn't need to be an elite defender though. That's not what I'm saying. He just needs to be decent enough not to be a liability on the floor. He's not an elite offensive scorer compared to the guys you mentioned (not including Harden right now) nor does he have the all worldy playmaking ability to help mask that aspect as well (not including Kyrie).
If you're going to be below average on defense, you need to at least be all worldy at something else to help make up for it. He's not that and dudes are bugging if you insist otherwise. You would not put him in that group of guys you mentioned when it comes to be all worldy offensive players when they were at their peak. Mitchell just isn't that.
In the playoffs you don’t even have to necessarily be a bad defender to be targeted or exploited. Gobert is not a bad defender was still targeted and exploited. Conley is not a bad defender was still targeted and exploited. Naturally because of his size even if Mitchell was to ramp up to a net neutral to slightly above average defender in the regular season it’s possible that in the playoffs he could be targeted and exploited. That’s why it’s important for teams to anticipate and build teams around that type of shyt.
Also, yes Donovan is that otherworldly on the offensive end.
I’m not sure how he isn’t. His playoff scoring is above these players you have listed. He has been an All-Time level playoff scorer. His regular season success as an offensive engine for the Jazz speaks for itself. His offensive impact numbers place him firmly in the top 10 overall offensive players in the game today and top 5 scorers.
His offensive impact comes from the fact he is one of the most efficient self creators in the game (57% TS, assisted on only 191 of his 670 field goals RS+PS) and his ability to make kick out passes to three point shooters for assists, hockey assists, and further motion that few players can make. He is one of the few players with a relentless offensive motor and bonafide three level scoring.
