Kurt Coleman was a liability... I wish him well, but glad he's gone

This. I've been thinking about that as well. Our Safeties don't make many plays. Is that because they aren't very good or is this scheme just not conducive to big plays from Safeties?

I'd like to think that it was the scheme but good/great Safeties find a way to make plays no matter the scheme. They just have a nose for the ball.

By the time Darren Sharper made it to NOLA he wasn't the fastest or most athletic player on the field but he had instincts. Brian Dawkins probably ran a 4.6 but he played much faster because of his instincts. Same with Ed Reed.

Last season there would be long stretches where you'd forget that Marcus Williams was even on the field. Seemed like he was always out of position. Maybe that can be corrected. Maybe not. We'll see.
I think Marcus is our only safety with a "nose for the ball" as far as interceptions. Bell has it in the run game. Marcus didn't make as many plays as he did as a rookie, but "sophomore slumps" are common, especially for players who have stellar rookie seasons. Marcus still flashed his ability in 2018, and I expect him to have his best season yet in 2019. If that happens, he will be one of the best safeties in the league, because his 2017 season was that good.

Marshon is in the same boat. Both he and Marcus regressed a little with their greatest assets. Playmaking (interceptions) for Marcus. Blanket coverage for Marshon. I expect both to be near the top of the league in year 3.
