The long and winding intern search has introduced us to some awfully bright folks, and that includes Max Wasserman, a college student at Cornell. He pitched us the idea that, using margin of victory – the most quantifiable indicator – the BCS bowl games have been less competitive than the pre-BCS Big Four bowl games. And before you argue that the BCS has brought us closer to finding a National Champion, Wasserman found this: If you compare the Division I-AA championship games (beginning in 1978) to the BCS championship games (beginning in 1998), the margin of victory is closer for I-AA title games. Further proof we need a tournament. Max’s analysis and charts after the jump.

I found the margin of victory of every Rose, Fiesta, Sugar, and Orange Bowl from the past 30 seasons, the last 10 of which have been under the BCS system. (Just so it’s clear, the margin of victory is the number of points between the winning score and the losing score. So for this season, the margin of victory for the Orange Bowl was three (Kansas 24, Va.
Tech 21).) Once all these values were entered, I found the average margin of victory for the past 10 or BCS years (1998-2007) and the average margin of victory for the 20 years before the BCS (1978-1997).

The idea is to use margin of victory as a measurement of the quality of the bowl game, with a lesser margin of victory implying a more exciting game. As such, I treated all overtime games (like the Boise State-Oklahoma Fiesta Bowl) as having a margin of victory of 0. This also served to keep things consistent with the tie games from before the overtime era. Obviously, margin of victory isn’t an absolute indicator of the quality of a game, as there can be close but boring games due to low scoring, or games that were exciting and only became blowouts towards the end. However, without re-watching and ranking the quality of every bowl game of the past 30 years, a true indicator of game quality cannot be quantified. As such, margin of victory remains the most quantifiable indicator.

As you can see from the results, the average margin of victory increased by at least a couple points each from the pre-BCS to the BCS era for the Rose, Sugar, and Orange Bowls. The Fiesta Bowl’s average margin of victory stayed the same, although it was greater than the averages for all the other Bowls in the pre-BCS era. This may be in part to the Fiesta not being a “top-tier” bowl game until the mid-80s. I also took the opportunity to average all the margins of victory for all the bowls in the pre-BCS and BCS categories (even factoring in the two National Championship games from the last two years into the BCS category) and found a two-point increase in the average margin of victory.

The purpose of the data is to show that the although BCS system may spark controversy nearly every year and may be loathed by college football fans, it’s not creating better games either. You could argue that before the BCS, the major bowl games were better when the organizers weren’t locked into their competitors. Do you think the Sugar Bowl would have taken Hawaii if the BCS didn’t mandate that the Warriors be selected? And what about the Rose Bowl being forced to select the Big Ten runner-up the past two years, resulting in USC winning games by 14 and 32 points?

Of course, then you get into the argument that before the BCS, the bowls would not always result in a consensus national champion. That’s when the playoff argument comes into play. Which is why I took the liberty of averaging the margins of victory for the Division I-A national championship games of the last 10 (BCS) years and comparing it to the average of the margins of victory of all the Division I-AA national championship games (from 1978). The results: Average margin of victory for D I-A championship games: 14.50 points. Average margin of victory for D I-AA championship games: 12.87 points. Just goes to show that if you want the best chance of having the truly best teams play for the championship, have a playoff. It’s better for everyone and everything. Except the Rose Bowl.
