In line with the comments above about the top tier, I ran across this list of FBS schools by winning % the other day. When you exclude the newbies (Boise, Kennesaw, Coastal Carolina, App. St., James Madison, Ga. Southern), it just runs straight down the list of who's who.
Ohio State, Alabama, Michigan, Notre Dame, Oklahoma, Texas, USC, Penn St., Nebraska
Tennessee, Florida State, Georgia, LSU, Miami (FL), Florida, Auburn, Clemson, Washington
