I think the general consenses is that wiggins, Parker, embiid, randle, exum and smart all have The potential to be franchise player. That group is alot stronger then any top 6 since the Lebron, melo bosh draft.
The top six in the '03 draft were James, Wade, Anthony, Bosh, and then David West (picked outside the lottery), and then, I don't know . . . Hinrich? Kaman? Korver? Mo Williams? Diaw?
The '03 draft is considered one of the best drafts in history along with '96 and '84. Each of those drafts had at most four bona fide franchise level superstars.
So, for the 2014 draft to have six (or seven . . . or more) franchise level talents, it would have to be not only on par with the previous greatest draft classes, but considerably better than any of them.
I just think some folks are setting their expectations a little too high for this year's crop.
2003 had 8 all stars - James, Wade, Bosh, Anthony, West and then Chris Kaman, Josh Howard, and Mo Williams. Aside from Howard, TJ Ford's career was also destroyed by injuries. Barbosa, Korver, Hinrich, Ridnour, Pietrus, Diaw, Pachulia, Collison, Bonner, and Blake were also all in the draft. That is the reason the draft is thought of so highly, you have the 4 HOFers at the top in addition to the 5-10 starter level players, and the 10 or so very solid career back-up level players. It was a great draft for that reason.
The 1985 draft had 10 all stars (including 4 HOFers) - Malone, Ewing, Dumars, Mullin, Schrempf, Michael Adams, AC Green, Terry Porter, Xavier McDaniel, and Charles Oakley. In addition, Sabonis, Tisdale, Gerald Wilkins, Spud Webb, Hot Rod Williams, Benoit Benjamin, and Tyrone Corbin were in the draft. Pretty solid draft that nobody ever mentions as an all time great draft, probably because 84 was so good at the top, but from top to bottom 85 was probably better.
