Division 1-A and 1-AA Should Reunite

This past Saturday witnessed 2 Div. l-AA (now called Playoff Subdivision) teams upset Bowl Subdivision teams, albeit the two losing teams were ACC bottom feeders Duke and Virginia. They both lost to Richmond and William & Mary respectively. There was very nearly a third upset when Iowa had to block not one but two field goal attempts by N. Iowa, a Playoff Subdivision opponent, to escape with a 17-16 victory.

The most famous take down of a Div. 1-A opponent by a l-AA team was Appalachia State's 34-31 upset win over Michigan in the Big House two years ago. What is my point in all of this? My point is that the top Playoff Subdivision teams can not only hang with but beat most Bowl Subdivision teams. Why was there ever a split in Div. 1 Football back in, I believe, 1978? I think both divisions should reunite. There have been more and more examples of Div. 1-AA teams not only holding their own but beating big time schools. I know it doesn't happen most of the time, but it seems more and more frequent of late.

Now, if this were to happen, you would have to create more bowl games for bowl eligible schools, and perhaps 1 or 2 more BCS bowls. These former Playoff Subdivision schools would get more money for their programs by playing in bowl games (money is what it's all about, right?).
Bottom line, I really don't see the point in having a Playoff Division and a Bowl Division. Just go ahead and reunite into Division 1 Football.
