I concur.
From a league perspective, I'd say the Rams are in a similar position as the Steelers which is enviable. Pittsburgh hired a successful young coach they will ride for a couple decades as can the Rams.
With that said, while the Pats, Chiefs, and Seahawks have some time left with their leaders, teams like the Rams, 9'ers, Cards, Bills, and Dolphins could be looking at Tomlin-like stability.
