 the Chiefs rode to a three-peat. And essentially, what could be the biggest stumbling block, what has been the biggest stumbling block for all these teams in the 60s and 70s and 80s and so on and so forth, they haven't done it. And I talked to a lot of guys, great players, Hall of Fame players in a lot of cases, who took a charge at that challenge and couldn't do it. And a lot of times what came up was, hey, we were exhausted. We had played a lot more games than other teams because we had been playing three games, four extra games a year, whatever the case was, depending on the era.
