You know that data is available, right? There were only 10 players on the d line with over 80% of the snaps. There were 40 defensive lineman with 70% and one of those was Greg Rousseau at 71%. So I think your perception may not be reality.
However, I always love to be proven wrong so I'm looking forward to the list of teams with their top 4 d lineman playing over 80% of the snaps.
