On another note, you can also win championships with a great defense and a good offense or offense that plays smart, doesn't turn the ball, and just takes shots down the field. The Patriots won numerous championships with the best game manager ever.
In 2018 the Rams were literally scoring over 40 a game and so were the Chiefs. They played each other and the final was like 53-49. The following week the Bears beat the Rams like 16-9 or something like that. Going into that game non-educated people thought the Bears had no chance against the high powered offense of the Rams. I believe the Bears go to the Super Bowl that year if they make the FG. By the way, everybody should realize the importance of a FG kicker after this past weekend.
I believe you need to be incredible at either offense or defense, good at the other, and outstanding at special teams to go the distance.
