He just said that at his press conference. They expect that some of last year's draft picks "will play a bigger role this year". THey chiefly mean DeMarcus Walker who was moved around - told to lose weight, then didn't have any impact at all as a 2nd round pick. He gained the weight back and is going to be a DE which they need.
That and Jake Butt didn't play at all. So, they have 2 highly touted players who should have an impact of some sort this season who had lost years last year and made the draft look so bad. (2nd round and 5th round picks doing essentially nothing).
Add in a year's experience for Garrett Bolles and their entire 2017 draft class should look a lot better this year. They certainly better hope so anyway.
