If he's healthy, I think the scheme change is going to do him...and 54, a ton of good. Lool at the film from 2018 and compare it to last year's. The d-line actually held their ground in 2018, allowing the linebackers to diagnose plays and flow to the ball. Last year, offensive linemen ran wild in the second level of the defense, negating both of their natural talent to shoot gaps and disrupt plays.
Look, I'm not making excuses for either of them. LVE has to figure out what's going on with and correct his health situation. 54 has to get better at focusing on the task at hand and stop allowing shiny objects to distract him off the field......but they both have talent and they've both played at a high level in this league, for this team. If Quinn is as good as advertised, with the addition of Neal and maybe a LB early, this group could very well become a strength again.
Just a thought
