Kyrie Irving (25 years old)
Dennis Schroder (24 years old)
Zach LaVine (22 years old)
Jayson Tatum (19 years old)
These 4 with have the backcourt spots in the East locked up for the next 5-7 years.
And without even mentioning other players, Fultz will simply not be good enough to even be worthy of all-star consideration. He'll be the 3rd wheel behind Embiid and Simmons where he will simply be a spot up shooter.
Eric Gordon is his fate.
He's 6 years younger than Kyrie and 5 years younger than Dennis, nevermind the fact that a dude playing in Philly is much more likely to get an AS vote over a guy in ATL.
Secondly, Tatum isn't a guard, he's a SF and will be developed with playing the smallball 4 in mind. I like how you say Fultz isn't a PG, yet a guy whose gonna be playing SF/PF for the first 4+ years of his career is a guard.
