I really hope this team doesn't try to force Mobley as an offensive creator this year. One of the best things about acquiring Mitchell to me is honestly that Evan won't be relied upon to be the 2nd leading scorer on the squad or anything. To me, Mobley's most effective as a sort of connective tissue on both ends. On defense, he shouldn't be your last line of defense. Because you don't want him being your biggest rebounder on the floor or banging with centers. But he can be the best help defender in the game at the 4. Just look at how impactful Giannis is defensively next to Lopez. I think a lot of people - mostly outside this fanbase - envision Mobley's long term future at the 5, but I think him next to Allen is actually perfect for his abilities.
And then on offense, this might make people think I'm being pessimistic, but I don't think his future is as a #1 or #2 scoring option. It's not a bad thing in my eyes, because I think very few bigs should fill that role on a championship-level offense. In the modern era, it's just not efficient ball to have non-perimeter guys creating so much, outside of very rare exceptions like Embiid, who's utterly unstoppable in the low post, and Jokic, who's a top 10 passer of all time regardless of position. Even KAT, who's probably the best big man shooter of all time and can pass, might not be an ideal offensive focal point in the playoffs. Giannis doesn't function like a big on offense since he can penetrate and create for himself and others from the perimeter like superstar wings, so I don't count him.
Mobley's young still, but in all likelihood he's not going to be an outlier shooter, passer, or ballhandler, and without the frame to get up to Embiid size of being physically overwhelming, you need to be basically all-time level for a big in 1, maybe even 2, of those facets. Those are things that typically you show very early on. It's going to be the fact that he can be "good" at all of those things while being a big that makes him valuable. I thing Mobley's road to being a top 5 most valuable player in the league ends with him being a high-level Adebayo of sorts. A #3 scoring option on offense who's your #2 playmaker out of the high post. And then maybe the best defender in the game. It would be a waste of what Mobley does excel at to try to force the high scoring output thing. It fits neither his strengths nor his personality, and would honestly hamper his development.
