The reason why is because if there's not enough 6 win teams then the 5-7 teams with the top APR schools would then become bowl eligible. Right now it is looking like there could be multiple 5-7 teams that will go bowling this year as a result. It depends on what happens this week, but I'd guess that there will end up being 2-4 teams that end up getting in through this method. Of all of the potential 5-7 teams Nebraska has the highest APR score meaning that they have a very good chance at still going bowling. Missouri is also near the top of the list (behind Nebraska, Rutgers, and Indiana). Odds of Missouri going bowling is more uncertain since they're a few teams down, but they still have a pretty decent shot at it.
