bizarre poll... "Parker and Lavine"... strange.
No, I don't think he will not be a top 2 player from his draft class. Not sure why you referenced those two players specifically.
His summer league performance gettin people hyped up. He wasn't even in the top 60 statistically. Aaron Gordon was #1, though. Dante Exum was top 10, though he only played a single game. There's always sleeper candidates... I wouldn't bet money on Smart being top 2 just based on Parker and Wiggins alone... the chance that nobody else surpasses Smart is unlikely.
A partial list of 2014 draftees who statistically outperformed Marcus Smart in this summer league: Aaron Gordon, Dante Exum, Dwight Powell, Rodney Hood, Noah Vonleh, Russ Smith, Kyle Anderson, Furkan Aldemir, Eric Green, TJ Warren, Adreian Payne, Mitch McGary, Zach Lavine, Lmar Patterson .. That doesn't include Wiggins, Parker, Nurkic, Stauskas and (obviously) Embiid who didn't play... it doesn't include Julius Randle who was on a minute restriction having only been cleared to play ball a couple weeks prior...
Clearly not all of those guys will end up better than Smart. CLEARLY. But I wouldn't put money on Smart being the second best player in this draft long-term. Bad bet. Too many variables. That's not to say Smart will not end up top 5. But top 2... unlikely.
