Few teams know Robert Quinn’s pass-rush ability better than the Seahawks, who used to be terrorized by Quinn when he played end for the Rams.

The 29-year-old has been a bad fit the past two years with the Rams and Dolphins and is now being shopped by Miami. The Seahawks should be interested.

Miami reportedly is so desperate to acquire draft picks that it is willing to pay part of Quinn’s $11.8 million salary as part of a trade — just as the Dolphins did with Ryan Tannehill, who netted a fourth-round pick in exchange for Miami paying $5 million for Tennessee.

The Seahawks should pursue a deal for Quinn, offering a conditional 2020 pick (fifth or sixth) in exchange for Miami paying half of Quinn’s salary.

The Hawks can afford $6 million for Quinn. And the pick could be conditional on whether the Hawks re-sign him after 2019; if they don’t, they could owe Miami a sixth-rounder instead of a fifth. They even could make it a 4/6 instead.

Quinn was a monster for the Rams from 2012 to 2014, racking up 40 sacks and 71 QB hits. Injuries cut his 2015 and 2016 seasons in half and then he switched to linebacker when Wade Phillips came to the Rams. He still had 8.5 sacks in 2017, but the Rams then traded him to Miami, where he had 6.5 sacks last season.

The Seahawks had two good pass rushers last season: Frank Clark had 13 sacks and Jarran Reed 10.5. They need another outside rusher. The guy who has 14 against them — Quinn’s most against any team — would be a good addition for at least a year.

Quinn would give Seattle a good veteran rusher opposite Clark in 2019, allowing Seattle time to see whether younger guys — Rasheem Green, Jacob Martin, a rookie — make any progress or whether the Hawks should try to keep Quinn.

John Schneider needs to try to make this move.
