Welll.....it would impact bowls...there are already bowls having a hard time filling teams...some cant get teams with winning records...take 4 more away...and it gets harder...and quality team also...take 4 more away...big bowls...sugar,rose, etc will be down to having really hard time...
And right now there are few really watchable games.....
And then throw in weather in December....( Michigan, Ohio, nebraska, etc).for hosting a playoff game...talk about making it hardto sell tickets considering travel........even great fans..
But i am not saying i disagree totally...
I like 8....4 works....but some thought in physical conception of playoffs
