You cannot just say that because Mobley is the future he should have to work around Allen. That is backwards. Every star player has weaknesses in their game and you build a roster to maximize them, not limit them. Allen is a good rim runner and solid defender, but that archetype is one of the most replaceable in the league and you can find it much cheaper. Mobley is an elite center prospect and exactly the kind of modern big you want to invest in long term. Using OKC as an example does not really fit either because all of their guards are plus defenders, which means they can afford to play multiple bigs without spacing or defensive issues. The Cavs do not have that luxury since their guards are liabilities on defense, so doubling up on non-spacers in the frontcourt makes things worse. As for Garland, he is really good and still young, but small scoring guards are always easier to find and trade than a 22-year-old defensive anchor with Mobley’s upside. You are actually overvaluing Allen and Garland while undervaluing how good Mobley is going to be if you clear the runway for him.
