Epps isn't really a backup level player as much as at worst a 3rd safety who will see the field for a certain role in specific packages but probably a decent full time starter if he bounces bck well. Look at the man's snap counts... which to me is one of the most underrated things in football.
in 2022 on the Eagles he played 99.10% of the snaps on defense and led the team in defensive snaps on the 8th overall defense. So on a D of that level he filled an important role and they didn't want him off the field.
in 2023 on the Raiders he played 91% of the snaps, best for 4th most on D. This was the 9th best D by PPGs.
In 2024 he only played 3 games (got injured in the 3rd... i don't know at what point in the game) and played 15.8% of the total snaps... so likely the vast majority of snaps until he got injured. For what it is worth in their first 2 games they allowed 22 and 23 points vs overall good offenses in SD and Balt... was it amazing D? No, but probably more in line with 2023 for the Raiders... and not 2024 when they ended up having 25th overall D without him. Now i am in no way shape or form saying Epps is the reason the Raiders dropped from the 9th best D to the 25th. No one defensive player is responsible for a 6 PPG swing. But it played a factor I'm sure. How large of one is something we can only guess.
People shouldn't dislike this signing. Epps IS NOT a camp body. He is better than not. Epps IS NOT the 4th safety on this team if he comes back form his injury. He is better than that. I look at his 1 year up to 4.4M contract and frankly. I think we got a pretty damn good deal.
