In my view, Bill last year had 3 main issues - a problem, a weakness, and a disadvantage (along with some other factors) that combined to affect his playing time and the perception of him going into this year.
Disadvantage:
Not playing in 2024.
Honorable mention - the injuries around him and defenses being able to adjust because of them.
Weakness:
Pass protection, but really just issues regarding the passing game in general.
Honorable mention - the fumbles.
Problem:
There were other factors as well, but we saw his play style change after the early part in the season. It was odd to see him suddenly reminding me of Leveon Bell - hanging out behind blockers waiting for blocks to develop when he had been hitting the hole so quickly early on. Briefly, I thought it was him growing as a runner, but then production dipped and he lost snaps. I believe the hype got to his head and he started looking for the home run instead of taking what was blocked for him. Rodriguez, who has always hit the hole quickly and violently, took the starting reps and the rest is history.
I think there’s still a role for him here - no other back on the roster has the high end explosion he has - but he’s got a lot to improve on for it to be more than a bit role. With the importance of explosive plays to OCs (and teams in general), while it’s certainly possible, I’d be very surprised if he were cut. I think it’s likely that they keep 4 backs, use a RBBC and the real battle is between Ford and McKissick with one of them going to the PS... presuming Allen looks like he belongs. Feel like McKissick’s ST play and versatility keep him around, but Ford’s kind of a younger version of JD, so who knows.
Voice_of_Reason - I don’t disagree with your issues with the corner position, but thought I’d share this quote below about Witherspoon that I came across. Doesn’t alleviate concerns with Amos’ health or whether Sainristil can work as a starter outside, but combined with the addition of Douglas, it does make me feel a little bit better about our depth. Still might have to rely on an elevated 6th corner at some point, so hopefully someone in that battle between Hamilton/Vigers/Rush/Davis/Hawkins steps up.
From “Rams expert” Bret Suter:
“Ahkello] Witherspoon established himself in the Rams' secondary as a plug-and-play contributor. He was a godsend in both 2023 and 2024 when he was virtually impossible to get off the field once he earned playing time.
"But injuries made him unreliable in 2025, and combined with other injuries, depleted the defense at the worst part of the season. When healthy, you can expect solid coverage. But good luck keeping him healthy. He is a solid addition to any team. But he will break fans' hearts if he is promoted to a starting role, only to be benched when injuries hit."
