The sport of college football has a very long history. In fact, it has 150 years of history.

Over those years, plenty of memorable moments have happened. Championships were won, monumental upsets took place and incredible stories were formed thanks to the sport.

Speaking of upsets, Sports Illustrated decided to name the top 10 upsets of all time on Monday. As far as Big Ten history goes, there are plenty of years to look back on and try to point out enormous upsets.

At No. 1 — according to Sports Illustrated — Big Ten fans will certainly remember this:

1. Appalachian State vs. Michigan, September 1, 2007

Final score: 34-32, Appalachian State

“Michigan paid Appalachian State $400,000 to come to Ann Arbor and play in the season opener against the Wolverines. The Appalachian State Mountaineers had won two straight FCS National Championships and were a powerhouse FCS program, but a matchup against a No. 5-ranked FBS program seemed like an easy win for the Wolverines. However, a 24-yard field goal by Appalachian State kicker Julian Rauch put the Mountaineers on top with 26 seconds remaining, completing one of the biggest upsets in the history of college football.”

This upset was seen as something unthinkable at the time. Even today, it can be looked at as absolutely massive.

This wasn’t some powerhouse program at a lower level coming up and nipping a higher-level school. This was a team that many haven’t even heard of taking down a blue blood of college football.

This wasn’t even a bad Michigan team. Teams have their highs and lows. Every program goes through it.

But Michigan, in 2007, was ranked No. 5 in the country. It was supposed to be much better than just about every other team in college football.

Michigan just wasn’t better than the best FCS school on that day.
