I'm not sure if it's Robert Quinn as I haven't seen him play. The Rams thought more of getting rid of him than keeping him. I'd probably say it's DeVante Parker. Every year we hear it's his break out year.
Miami Dolphins: Robert Quinn, outside linebackerhttps://www.yardbarker.com/nfl/articles ... 0_26389343
Since inking his huge contract with the then St. Louis Rams back in 2014 following his 19-sack 2013 season, Quinn hasn’t lived up to it. The past three seasons in particular have been mediocre ones for the former first-round pick, as Quinn has totaled 17.5 sacks since 2015. The Dolphins swung a trade with the Rams this offseason to land Quinn and see if he’s worth keeping around for the long term. That’s debatable, and Quinn will have to prove he’s still a fearsome pass rusher this year or likely be cut before 2019, when the guarantees run out on his deal.
