Wiggins is pretty good on transition ball imo, but his other games lack so I don't think he'll be an positive impact from the first season. Give him 3, 4 years.
As for Smart, he looks like a Avery Bradley on defense, but also an inefficient version of Corey Maggette on offense. Is he a star? I think so but kinda like Wade he can drive in, but just like him his shooting needs to improve and translate well into NBA.
