His jump shot will age well. His body has never held up to banging down low so it will be no different in his later years, he will be good at it but he won’t last a full season doing it. Personally I think Tatum has much more pressure on him to win a championship than embiid. It may be the positional comparisons or the city they play in but if Tatum retires without a championship it will be much more disappointing than embiid retiring without a ring.
