I wouldn't say its an impressive draft but it isnt as bad as some people want to make it out to be.
Looking at resent draft history 2011 and 2013 where both considered to be weak classes.
2011 yielded a lottery that includes 2 Star (irving and Thompson{leonard went 15}), 2 High production starters (Walker and Knight) and 3 Busts ( Williams, Vessely and Jimmer). The rest of the lottery ranges from solid bench player to solid starters. An Ok group but not overwhelmingly good. Howver looking past the lottery and the first round yielded Leonard, Vecevic, Harris, Faried, Jackson,Mirotic, and Jimmy Butlter. The 2nd round Parsons, and IT4. In terms of total talent thats a great group.
2013 is still a young group but at this point I feel safe saying that its best players in no real order are Giannis (#15), Gobert (#27), McCollum (#10), Oladipo (#2), Noel (#6) Crabbe (#31), KO (#13), S Adams (#12), Schroder (#17), and Dieng (#21) i'm prob missing someone... This isnt an overwhelming draft class but the talent is there. It just once again isn't coming from the top end of the lottery as would be expected.
This years draft for all its detractors has two players who would be in the debate for the #1 pick in most years in Ingram and Simmons. Where I see this as a weak draft is the group that rounds out the lottery. I personally am really high on Bender and Poeltl (despite Sabonis), I also like Murray, Hield and Ellenson. I am not really high on Dunn, Brown, or Labissiere as early picks (I wouldn't not draft them do to their potential but I would be worried). In my opinion what makes this draft interesting is the mix of proven college players and really really raw prospects. Players like Hield, Valentine, Brice Johnson, Prince, and Hayes should all be able to carve out various roles in the NBA. Guys like Labissere, Diallo, Chriss, Brown and Rabb have a ton of high end potential but are also major bust risks. Drafts like this will make alot of teams look really bad for drafting busts while a hand full will come out looking brilliant for drafting an allstar in the 20s.
Lets hope DA is on the good side of this one.
