Towns, Russell, Porzingas, and Booker all had immediate impacts and they were young. This years draft class has just been shit.
The upcoming draft is best in years. You'll have immediate impact players.
Fultz would be a starter for most teams.
Ball's a wildcard.
Jackson would be an above average NBA player already in all aspects except for shooting (which isn't necessarily a big weakness)
Isaac needs strength, but I think he's better than Ingram.
Tatum would probably start for us at SF as a 3rd ball handler/scorer as he can also spot up and shoot
Markkanen would be our starting PF as a shooting big who can go inside and play some defense
You'll also have more guys 10-30 making immediate impacts than most years.
