One of the many things I point out to people when I’m talking football is that winning games in the NFL is very hard. I think NFL football is the epitome of modern sports because of it. You need good players who work together in sync to execute plays that good coaches have created who were hired by a GM who’s hiring the best people he can so that the team can win games.
There are a lot of moving parts involved, and when you are missing the “good” pieces of any of the multitude of cogs that make the machine of winning in the NFL work, it makes that task extraordinarily difficult.
