My most positive way to look at it is that the whole list contains 3 players from playoff teams.
Nikola Mirotic - 24 years old, has played professionally since 2008
Marcus Smart - 21 years old, first professional season
Bojan Bogdanovich - 26 years old has played professionally since 2004
Also, I expect him to play with a chip on his shoulder.
And double also, these are based on rookie year performance, not whos the best prospect. I think nearly everyone would prefer Smart to Clarkson long term, and I personally think he will have better careers than everyone but Wiggins and Noel assuming this year wasnt an I play in Philly mirage.
Worth noting Parker, exum, randle, Gordon are complete question marks right now.
