I agree, but would phrase it a different way.
The Bears have no defensive lineman that requires the offensie to double team him. Yesterday, the five OLs of the Jets were able to handle the 5 pass rushers without the tight end or even the running back to be used as blockers. The value of a stud rusher is that he requires two blockers to handle him. And two studs require four blockers, which means that the other three rushers are free to stunt or overpower their single blocker. If we had one stud DE and one stud DT, Gipson or Robinson would be perfectly acceptable, and probably better than average, pass rushers. I haven't seen enough to know if they could handle the running game.
It would be great to have 4 or 5 stud rushers, but that isn't the world we live in.
But when we go out to get the studs for the team, we had better bear in mind that if Fields goes down, the Bears go down.
