The current 5 year run of the Chiefs somehow passed that same longevity test?
I didn't say anything about Reid's Chiefs, but looking objectively...
With Mahomes, they are like our 1990's team, except they have one more Superbowl appearance in one less years.
When you look at Reid's tenure beyond and including Mahomes, he has nine straight playoff and six straight AFCC appearances, won 12 or more games six times, and 14 or more twice.
Dallas went to the playoffs six straight times, had four straight NFCC's, won 12 or more games three times and have never won 14 games in our history.
The Chiefs just repeated with minimal WR or RB talent to speak of and there's no end in sight. Meanwhile we were 6-10 by 1997, two years from our last Superbowl.
By what objective measure are they lower than Dallas?
