Sorry, these arguments about scheduling weak opponents hold no water.
What do D1 basketball teams do? If you play a powderpuff schedule you will not get to the big dance unless you are conference champion. D1 football is the ONLY college sport at any level with no playoff. You're saying all the other sports and all other college football divisions don't know what they are doing?
The BCS is designed to protect the income for traditional programs, even if their current teams don't deserve it.
So what you're telling me is that teams that don't play non-conference powderpuff schedules and lose will be given more "weight" that those that don't? How can that be? That sounds awfully subjective doesn't it? Would a 3 or 4 loss SEC or Big 12 (or other major conf) team deserve more weight than a 1 one loss Mid-America team? In the case of 4 losses...what if all those losses were to top 10 or 15 teams when the loss occurred? Again...it's subjective...someone is going to get hosed and everyone will argue about it.
I'm not saying other conferences don't know what they're doing, I'm sure they do. In fact, I like the idea of a playoff, however, I'm playing devil's advocate here. When you consider what's happened in Div 1 basketball throughout the years, you could infer, that the result at the end would be the same. The winner of the big dance has basically been one of the top teams during the year anyway. Same would probably hold true in football. The end result would be the same, the path to get there would be different. And for many, a lot less enjoyable. People are bowlitized (that's a new word)...they like them. Change is hard for people.
I'm curious as to how many teams would be involved in a playoff, etc.
