Looking back at some of the final mock drafts from last year to get a glimpse of how accurate they are. I looked through 14 picks, since there weren't any trades before that point to confuse things.
Asterisks on correct picks.

McShay got 7/14 right, Kiper and WalterFootball got 6/14, Mayock and Banks got 5/14. Everybody got the two QBs and Cleveland's pick DT Danny Shelton at #12 right. Nobody got the Redskins taking Scherff at #5, Jets taking Wiliams at #6, or Rams taking Gurley at #10 right.
All 5 mocks had the same top 5 guys in some order: Winston, Mariota, Fowler, Williams, and Cooper. All but Williams did go in the first 4, Williams fell to #6.
