Although the Seahawks traded Frank Clark, have L.J. Collier sidelined for a while and Ziggy Ansah still yet to fully participate in training camp, they feature an additional pass rusher in Barkevious Mingo. The former first-round pick is now a full-time defensive end, Bob Condotta of the Seattle Times notes. The 28-year-old defender worked as an outside linebacker in Seattle’s 4-3 scheme last season but came into the league as a 3-4 edge. That has never translated to sack production (10 in six seasons), but it looks like the Seahawks will attempt to see if Mingo’s first NFL work as a full-time lineman can.

“That’s what I came into this league to do,’’ said Mingo, who played 545 snaps last season with Seattle. “I came into this league to rush the passer. And teams I’ve been on before, they’ve had a different idea of what they wanted me to do. And that’s OK. … But looking back at it, I’m happy I get to go back and do it (rush the passer now). I wish it would have been a little earlier in my career. But still, I’m just excited for the opportunity to go out there and just help the team.”

Moving first to some backfield situations, here is the latest from some of the NFL’s Mountain and Pacific Time Zone teams.

• While Pete Carroll said 2018 first-rounder Rashaad Penny had a “great” offseason, the Seahawks still appear to be leaning toward keeping 2017 seventh-rounder Chris Carson as their starting running back. Penny is not playing on the same level Carson is during camp, per The Athletic’s Michael-Shawn Dugar (subscription required). Penny, though, will be a bigger part of Seattle’s offense than he was as a rookie. Mike Davis‘ Chicago relocation will ensure the San Diego State alum sees more time.
• Theo Riddick visited the Broncos and Saints before deciding on Denver, but the six-year Lions back said (via Mike Klis of 9News) 10 teams reached out after Detroit released him. Riddick, 28, signed a one-year, $2.5MM deal to join Phillip Lindsay and Royce Freeman in the Broncos’ backfield equation. The longtime pass-catching back took reps with the Broncos’ first-string offense in his initial practice with the team.
• As for where that leaves Devontae Booker: Klis notes there is a chance the team keeps four halfbacks and fullback Andy Janovich. However, Booker may now be a trade candidate. The Broncos used former California high school sprint champion Khalfani Muhammad in all four quarters of Thursday’s Hall of Fame Game.
• Matt Breida may join Booker on the trade block, though that is not certain yet. The 49ers have one of the NFL’s deepest backfields, with Breida joining Tevin Coleman and Jerick McKinnon. It’s been posited the 49ers will not have room for all three on game days, considering Raheem Mostert was re-signed for his special teams ability. A way Breida (5.3 yards per carry last season) could see time will be as a kick returner, Matt Maiocco of NBC Sports Bay Area writes. Breida has only returned five NFL kicks, all coming in his 2017 rookie year.
• Seahawks recently waived tight ends Justin Johnson and Tyrone Swoopes cleared waivers and will revert to the team’s IR list, Condotta tweets.
