Although I greatly enjoy your writing, I do take exception to basic facts being dismissed as “ignorance” by another reader. In your response to my previous comment, you acknowledged that having more teams to compete with made it harder to repeat, but asked if the Chiefs really had to outdo 31 other teams given the structure of the playoffs? And you ended with, “Mathematicians out there: Is it possible to come up with an algorithm to determine which scenario would be more difficult?” I took that as a rhetorical question, but having been called ignorant for understanding the math homework my 14-year-old brought home from ninth grade, I will entertain those as serious questions. Did the Chiefs have to beat 31 other teams to become champions? No. Lombardi’s teams didn’t have to play the whole league either. I leave it to you as our historian to check to see if Curly Lambeau’s teams played every other team in each of those three years. But the odds of winning a championship are always one in however many teams are in the league. If you want the algorithm to calculate that based on the current playoff format, here it is.
