you named a whole mess of attributes and precisely two of them translate to losing a step to age or injury, dude: finishing is a product of his innate athleticism and blowby potential, his playmaking is a product of his gravity, his rebounding is a product of his build and height and his rim protection is a product of his incredible ability to recover and leap
his footwork and his defensive positioning may translate, but that's really all you're going to maintain into the twilight of your career if you don't age as gracefully as lebron
I know it sounds silly because Miami's so stagnant on star trades, but I'd really love him here as a Herro upgrade, just because his rim pressure is so much more noticeable and Herro's only real gargantuan flaw is that he's entirely incapable of taking defenders off the dribble.
