Every three or four years, NFL personnel, schemes and coaching staffs change — so teams must be able to adapt to how football is now being played around the league.
We’ve seen this with the Kansas City Chiefs. When quarterback Patrick Mahomes took over in 2018, the team built its offense around speed at wide receiver — and Mahomes’ ability to throw downfield. The Chiefs were consistently getting five players out on routes while offensive tackles were on islands, focused on pass protection.
So when defenses began running more two-high safety coverages to limit explosive plays, Kansas City evolved by becoming less dependent on its speedy receivers, investing more into the offensive line and playing more 12 and 13 personnel to mix in the running game.
