Honestly, most of the time I can see the other side of an argument, even if I don't agree with it.
But to those who don't want playoffs, I understand their thinking perfectly.
Their reasons are:
a) We make a lot of money now, and change brings uncertainty.
b) We have a nice crony relationship with the existing bowl structure, and don't want to ruffle feathers.
c) In a playoff system, people outside our close-knit circle of cronies might get some of the money and/or power.
d) Our boosters are corrupt good ol' boys who resist change, and we don't want to risk angering them.
e) We have to make up phony reasons other than money because "officially" we are non-profit ins utions in the business of educating people, rather than franchises in a sports league where we get away with not paying the players and get to keep all the lucre for ourselves and our friends.
f) We don't really care about compe ive integrity anyway; it's all about $$$$$.
I'm probably forgetting a couple of reasons off the top of my head, but they are just as obvious.
