He's been a 4-3 DE last three years

doesn't have to cover like he did in a 3-4 defense.

So he rushes more and has more opportunity for sacks --- so it's a good scheme fit for him. That and he has to have improved his game
with experience working on his skills.

Always like to see former Rams do well after they leave ... he and Obo, to a lesser extent, are capable rushers
