Let’s not even start talking about Kenny Clark not being an impact player as an all around run/pass defender.
I won't go so far on your other statements and projections, but I agree with this. Kenny Clark is one of the better all around DTs in the league.
College isn't cranking as many of these guys out anymore and Clark has been very good for a long time. He's clearly their best DL, Brooks might be the next best. This team looks different/worse without him on it.
Kenny isn't going anywhere, they will probably give him an extension and rework some of the money he's owed this next season for room.
