If you only look at situation, 2013 was destined to be an elite draft. If you ranked a 2013 rookie by anonymous team/position combos it would have looked something like: GB RB, DEN RB, PIT RB, SD WR, STL WR, CIN RB, PIT WR. With a few tweaks that's a close match to what y+1 value is.
In stark contrast, the 2014 class lands in a terrible situation. Based purely on situation, a 2014 draft would be TEN RB, CLE RB, JAX RB, OAK RB, IND WR, DET WR, HOU QB, GB TE, NE TE, PIT WR, CAR WR, WAS WR, BAL WR, OAK WR, KC WR, BUF WR. There's very little to get excited about. The teams that need RB are bad. The good teams that need WR need them to be WR2s.
The wildcard is ATL RB but they have too many needs at OL and D, don't have a 2nd rounder, and may try to trade up from 1.6 for Clowney.
Immediate impact of the 2014 draft class might be minimal. If all this presumption is true, the way to exploit it is to trade 1sts. There are a ton of nice prospects in this class but none or few can't miss ones. If you get "draft day" value for a 2014 1st, what is holding you back from trading?
