The 2014-15 class has way more depth.
With hindsight, the main good guys of the 2013-14 class are IMO:
Oladipo, KO, Noel, MCW, Hardaway Jr, Burke, Giannis, Plumlee. Even some of the all star rookie team have not entirely convinced me (eg Cody Zeller).
Again with hindsight, the top-5 of the 2013-14 class is one of the weakest ever (Bennett, Oladipo, Porter, Cody Zeller, Alex Len). I cannot even think of another year with such a weak top 5.
2014-15 has way more talent: Wiggins, Parker, Smart, Exum, McDermott, Embiid, Young, Stauskas, Pap. Not all of them have got enough playing time, some (like Young) play mostly in the D-league, Embiid is injured but still...
I am just saying the obvious, but in the long run they are way more likely to turn into better players (with the exception of Giannis and Oladipo).
