You are missing my point.
Football teams have a number of goals. They include quality of play, and results. There is a best team at running the ball, stopping the pass, pulling out late wins in the clutch, winning on the road, special teams play, as well as having the best overall season cumulativelty counting every game (ie the team perceived as 'the best'), and winning a championship.
There are different talents and qualities that separate teams in each of those areas. (Staying healthy is also a part. You can't be the best team if you can't field the best team even if people think you are better if you don't have injuries) But whatever the talents and qualities are that determine which team survives and wins the championship are the ones that mean the most.
I think its crazy to consider a team that couldn't get their main objective accomplished on the field better than one that did.
