The Lions will ship defensive back Quandre Diggs and a 2021 seventh-round pick to the Seahawks for a 2020 fifth-round draft pick, Tom Pelissero of NFL.com tweets. 
Diggs, 26, was asked to carry more of the load this year after the Lions moved on from Glover Quin. The safety started in five contests this year, notching 20 tackles in total. For his work, Pro Football Focus has him graded as just the No. 61 ranked safety in the NFL, but, historically, PFF’s advanced metrics have held him in high regard.
Diggs is signed through the 2021 campaign thanks to the three-year, $20.4MM extension he signed with Detroit back in 2018. Still, the Seahawks can easily escape his deal, if they want to, after this season.
The Seahawks’ secondary is a long way from the Legion of Boom days and an experienced player like Diggs was badly needed in Seattle. Still, the Seahawks’ training staff will have to give Diggs some attention if they want him to stay on the field – the former sixth-rounder has seen limited snaps since Week 4 due to hand and hammy issues.
With Diggs in Seattle, the Lions will move forward with Tracy Walker, Tavon Wilson, and Will Harris as their top guys.
The tank is on
Good pick up for Seattle
For the price of a 5th they got back a 7th and a solid player, what’s not to like
Man, I feel the Lions are so close. They’ve had some bad luck losses and they also played at the end of some game but I feel they are close. I guess this one trade ones change for them but I hope they don’t trade anyone else. Not a Lions fan but I am pulling for them, pulling for Patricia and for Stafford and I feel bad for their fans, they’ve been so close and it all went down hill but it seems like they are on the right track.
That being said, this is a nice get for the Seahawks I think. As much as I dislike that team lol. I think they need to trade for a TE though. Maybe McDonald from Pitt. since Hooper isn’t going anywhere with Atl
As a Lions fan I say “What the F$&@???”
I’m not even a Lions fan and I was thinking the same thing! Is their GM stupid?
C’mon Lion fans, Diggs is a show boating bum!!
I’m not defending Bob Quinn because he hasn’t done anything yet to trust him but…
They obviously trust Walker to replace Diggs and they dumped his salary and got a 5th Rd pick.
What sucks is Seattle is gonna use Diggs for their playoff run and then dump him at the end of the year. The trade nullifies his guarantee money so really Diggs is screwed.
