Neither is Justice Winslow he had more hype than just about anyone
Winslow is already a top tier perimeter defender and posting pretty solid state when you realize he's probably the 4th-5th option on the floor because we have Green, Dragic, Bosh, Whiteside, Deng, and Wade as our primary offensive options.
Dude has guarded multiple superstars, consistently, and he played them great.
Winslow is already ahowing signs of maturing into a Draymond Green type player with great/elite defende, high basketball IQ, high motor, and an all-around impact player.
Ask any dude here that's watched more than 3-4 Heat games and they'll tell you that Winslow's poise, decision making, and ability to make the right play is more seasoned veteran than rookie.
