This is a good point. Apart from the Pats, no team sustains winning for a decade anymore. The window is 3-4 years. Even with Mahomes, the guy is eating up a lot of $ to pay others. Those others won’t stay around for free. Can KC hit on cheap free agents and/or draft picks? Maybe. But the Packers and Rodgers certainly aren’t some dynasty. Some clever DC might figure their O out in some novel way too. A lot can change. Focus on making the Bills better and we will see what happens.
