I oppose a playoff in college football.
I do not oppose all playoffs. The NBA Playoffs are an example of a fairly reliable playoff. Major League Baseball has a well-structured playoff in concept, but it produces some strange champions, likely due to the nature of that game and just how much luck and other noise can override the ability gap between some teams (read Moneyball, kids).
The NFL's model is terrible. Same with college basketball. They're exciting, but they're basically dressed-up one-and-done tournaments, not championships.
For various reasons already well documented, there's no reasonable way to achieve a meaningful, representative, true championship through a playoff in college football.
Being as this is a website called College Football Resource, it should be implied and understood when I'm talking about playoffs that I'm talking about them in college football. I use examples from other sports to illustrate my arguments, but in reality I have no interest in advocating for change in their games. They are simply the examples when I discuss them. Sometimes I mock, but my real focus here is on college football, other sports be damned.
