#7. Los Angeles Rams: Greg Robinson
PFF grade (position rank): -36.2 (73rd)
2015 salary cap hit: $4.8 million
Robinson was the No. 2 overall pick in the 2014 NFL Draft, but he sure hasn’t played like it since entering the league. In fact, he’s gotten worse.
After grading out at -21.4 in 2014, Robinson ranked 73rd out of 76 qualifying guards in 2015 with a -36.2 rating from Pro Football Focus. He allowed four fewer sacks this season while playing every snap, but was responsible for a league-high 19 QB hits.
Disappointing offensive linemen aren’t as visible as underachieving quarterbacks like JaMarcus Russell and Ryan Leaf, but Robinson deserves to be listed among those draft busts. He’s still just 23 years old, but it’s hard to envision much improvement forthcoming.
