Of course he has some flaws. Take away those flaws and he's Stephen Curry.
Shocked? Look at their offensive numbers last year playing alongside Durant/LeBron. Steph is one tick above.
A motivated Irving with a new coach, new teammates, new ownership, new fans absolutely has MVP potential. If he was already an MVP, he wouldn't be available at any price.
Overpaid? Please. That's sour grapes. When's the last time a player on Irving's level was traded for less?
