Yeah and Tatum is alot further a way from that physical prime than Siakam, you cant put a celing on Tatum either he played amazingly well after the all star break and frankly looked like one of the top 10 players in the league and had larger improvement than Siakam this season. Were talking about who will be better in the future, nobody is putting a cap on Siakams development just he literally cant improve at the same rate year on year the improvemnt will become more incrimental like all players the more they play in the NBA. With the age difference and the way Tatum looked post all star break, if youre asking the question right now who will be better in a few years let alone when you compare Tatum when he reaches the age Siakam is now to Siakam now and ask who is the better bet for the future my money and frankly most people money is on Tatum becuase it is alot more likely hell be a better player. None of that means that Siakam isnt currently amazong and cant get better himself.
