Seattle had basically a 60/40 split in yards between Walker/Charbonnet. With Charbonnet probably out as an effective back in 2026 (ACL), they need a second back. On top of that, Charbonnet is only signed through 2026 and Walker is currently a free agent.
While I wouldn't expect Seattle to spend a 1st rounder @ RB if they resign Walker, 2nd round does make some sense.
The author of this "prediction" by the way is not right in the head. The Titans aren't going to use the #4 pick on a RB because they have more important needs, especially on defense and WR. And #26 for Fields seems a bit rich for his skill set and the Bills need a deep threat, not a possession threat.
