I think 8 teams would be perfect. What we're seeing right now is that with 4 teams, a couple of them are pretty much already per-determined at the beginning of each year and the others almost always come from the usual suspects. But with 8 teams, you're almost always guaranteed a few surprise teams per year.
With the current system, a non-blue blood like Iowa needs a perfect season to be assured of making the playoffs. Look at this year. With one loss already we're not out of the playoff picture. But even if we win out could possibly be on the outside looking in depending upon what happens in other conferences. With 8 teams, if we win out we'd be assured of being in.
Another way to look at it is this. In 2002, 2009, and 2015 we didn't make the BCS or playoffs. In the final BCS standings of 2002 we were #5 with a 2 loss USC ahead of us. In 2009 we were #10 in the final BCS standings. In 2015 we were #5 in the final CFP standings. Outside the top 4 every time during 3 of the greatest seasons we've had in modern history.
But switching to 8 teams since the beginning of the BCS era we would have made the playoffs twice and been just outside of the playoffs one more time. I think that is exactly what we would have deserved in each of those seasons. If Stanzi didn't get hurt in the NW game in 2009, we likely would have made the playoffs that year too. Three times in 20 years isn't too bad for a program at the prestige level of Iowa. I'm sure there are a few other fanbases, like Wisconsin(5 times in the top 8 end of regular season AP poll), Michigan(4 times), MSU(4 times), PSU(3 times), Nebraska(2 times) in the Big Ten, that would approve of such a change too since the beginning of the BCS era. OSU has 14 times in the end of regular season AP top 8 during that time frame though compared to their 7 times in the BCS championship or playoffs, which goes to show how no matter what we will still have the same bluebloods in almost every year.
