Carson ran for a combined 2,381 yards between the 2018 and 2019 seasons, becoming something close to an RB1 in fantasy circles, but struggled to stay on the field as he dealt with the neck injury that eventually required surgical fusion. It's not entirely surprising to see him retire as most of the offseason chatter about him was focused on if he'd be able to play this season. Rapoport notes that Carson won't file retirement paperwork with the league just yet. This clears the way entirely for Rashaad Penny and Kenneth Walker in Seattle's backfield. The Seahawks released Carson with a failed physical tag. 

This would be the worse of the two fusion surgeries, as multi-level ACDF is harder to come back from. Ex-Giants RB David Wilson retired at age-23 after the surgery, while former Colts RB Ahmad Bradshaw returned in nine months. Carson was cleared to work out in June. The sixth-year veteran is committed to playing this year. Whether he'll be cleared comes down to Seattle’s training staff.

Johnson participated in Saints' minicamp on a tryout basis. With Alvin Kamara facing a suspension, it's not a great sign he didn't land a deal. The 30-year-old is limited to pass downs at this stage of his career, averaging under 4.0 yards per carry three of the last four seasons.

It's pretty much what Pete Carroll said yesterday. “I see myself playing until I feel like stopping. My mindset is never to give up. So, I’m staying positive like I said, and continue to fight and get back onto the field," Carson said. The positive vibes are to be expected, and Carson's resiliency in the face of a career-threatening injury is to be lauded. But don't bank on him overcoming this if you can avoid it. Rashaad Penny and Kenneth Walker are shaping up as the backs to have in Seattle.
