The Toolbox: Home Field Revisited

In thinking longer about this morning's nerd tidbit regarding who really has homefield advantages, I latched onto the idea that certain conferences have different baselines. As Year2 mentioned in comments, in a conference like the SEC, almost everybody has a loud, large crowd, and you're more likely go grow accustomed to it.

So what if we were to adjust teams' homefield edges based on the conference median?

Below is how teams rank when you compare their initial homefield edge to the conference median, then apply the difference to the national homefield median of 3.5 points. But first, here are the conference medians themselves:

Conference Median
Homefield
Edge
ACC 2.45
Big 12 4.27
Big East 3.87
Big Ten 3.50
Conference USA 4.67
Independents 1.85
MAC 3.57
Mountain West 3.67
Pac-10 2.59
SEC 2.28
Sun Belt 4.17
WAC 5.51
NATIONAL 3.54

In the SEC, ACC and Pac-10 (yes, Pac-10 -- we're talking about history, not the present), the homefield advantages have been minimal. Teams like Arizona State, Florida and Virginia tend to have larger home-road splits than other teams in the conference, but for the most part the numbers are low. Meanwhile, the teams in the Central and Mountain time zones get a little crazy. Homefield in the Big 12 is significant, and the WAC is even moreso. (And since we're using the median, Hawaii's and Boise State's unique advantages don't skew the WAC averages even further.)

Anyway, when you compare individual teams to their conference median, you get an "Adjusted Homefield Edge" measure of sorts. Looking at things this way gives no love to LSU's Death Valley, but The Swamp passes the test.

23 Nebraska 6.2 Big 12 4.3 5.1
24 Rice 6.8 Conference USA 4.7 5.1
25 Kentucky 3.3 SEC 2.3 5.1

Since my Missouri Tigers are heading to Sun Devil Stadium in early-September, this isn't really what I wanted to see...

(And again, this is looking at the teams with the largest home-road splits. So what it is saying is that a team like LSU might play great in front of the home crowd, but it's also rather likely to play great away from the home crowd, therefore negating what we would consider to be their homefield advantage.)

Full list after the jump.
