Lets give it a few years before we come down to conclusions. The 2014 draft certainly disappointed due to all the hype, but to say its garbage is kinda hasty. We still have yet to see Joel Embiid or Julius Randle, two of its top prospects, play a single NBA game. Marcus Smart, Aaron Gordon, and Jabari Parker all missed substantial time this year and remember, they were rookies. Rookies seldom take the league by storm in their first year. Wiggins definitely lived up to the hype (in fact I think he exceeded expectations) but his team still sucked. Exum and Stauskas are a bit troubling but again, they are rookies.
Remember in 2013 when people thought that was going to be one of the worst drafts of all time? It turned out to have the Greek freek, Gobert, Noel, Oladipo, and Carter-Williams. Not to mention guys like Len, Porter, McLemore, McCollum, Adams, Dieng, Muhammad, Zeller, KCP, and even Olynyk look like they'll have nice careers in the league as time goes on. Pretty good for a draft that didn't have high expectations especially since its #1 has sucked.
You know who won the ROY in 2009? Not Blake Griffin or James Harden or Stephen Curry. It was Tyreke Evans, and if you look at the draft now and who was taken then, it's debatable as to whether or not Evans was even amongst the 10 best players taken in that draft. Heck from what I remember, Brandon Jennings was Evan's competition for the ROY back then. Those guys are good players, but they aren't great. Griffin, Harden, and Curry all came up a few years later.
The point is give the draft some time after 1 year. You never know if the 2014 draft has a Rudy Gobert lurking in the trenches.
