Hmmmm, took me a while to notice this one topic but here is a study that might be germane to the discussion. This is a comparison that I did not long after the 2006 NC run (so it doesn't include the latest BCS champs).
I'll just copy and paste it as it's a little lengthy:
Rating the BCS Champions, Margin of Kickassness
Reading some other boards and have seen the topic of 'rating the BCS champions' crop up a few times. There is a very good (and long) thread on the Florida board that surprisingly kind of sidetracked into a '95 Huskers vs. '01 Canes debate (surprising because it's mostly being argued by Gator's and Buckeye's). But generally the ontopic consensus is pretty favorable to our Horns but some of the reasoning got me thinking of a way to try and quantify the situations (while including the 95 Huskers as they are thought to be probably the most dominant team in anyone's recent or past memories.
So here's my metric; take the point totals from each opponent the champion played but subtract their head-to-head game and then divide that by the total games played (minus one) to get the opponents average score per game, both for and against. Then take that average and compare it to the head to head game played to gauge how much better (or worse) the champion faired compared to their season's opponent's average. In this way a team is not overly rewarded for beating the crap out of a patsy (cause everyone is going to beat the crap out of the patsy so their average will be very high) and conversely the team will be rewarded for scoring (or defending) particularly well against teams that had very good seasons.
So for the 2005 Longhorns for example, against USC they held them -12.00 pts below their average (38 pts versus an average of 50 pts scored per game) and the Horns gained a margin of 19.67 above what USC's defense was used to giving up that year (41 pts compared to 21.33 average). Combine the two and you get 31.67 pt margin of Kickassness. From there it's simply a matter of totalling up all of the games and averaging it out to come up with a Seasonal Margin of KickAssness, a figure to determine and compare how dominant one team was over their opponents during their championship run.
some notes;
1) Div 1AA game didn't count for the Champion (but I did leave in Div 1AA figures from their opponents totals, mostly because I'm lazy and because it didn't happen all that often and I don't think it skews the figures too much anyway).
B) if a team had to play another team twice during the season, both games totals were subtracted to get the opponents average and then each game was compared independently to that figure.
III) I threw in 2005 runner up USC (cause I thought they'd have a pretty high figure themselves) and 2006 runner up Ohio State (mostly to establish that these numbers don't mean ****, that even if you have a dominating season you can still get whooped in the title game).
So minus the spreadsheet ********, here's how it turned out:
Total dominance (combined Offensive and Defensive margins)
[pre]
1995 Nebraska 42.92
2005 Texas 40.46
2001 Miami 37.91
2005 USC (#2) 35.03
2004 USC 30.15
2000 Oklahoma 29.99
1999 Florida State 28.24
2006 Ohio St.(#2) 26.09
2003 LSU 24.72
1998 Tennessee 22.80
2006 Florida 19.99
2002 Ohio State 19.72
Offensive dominance (how much more the Champion scored then their opponent was used to giving up on average)
[pre]1995 Nebraska 29.17
2005 Texas 27.14
2005 USC (#2) 24.13
2001 Miami 20.59
2004 USC 16.03
1999 Florida State 15.80
2000 Oklahoma 13.52
2006 Ohio St. (#2) 13.19
1998 Tennessee 10.58
2003 LSU 9.03
2006 Florida 7.95
2002 Ohio State 2.38[/pre]
Defensive dominance (how much less opponents scored on the Champion than average)
2002 Ohio State -17.34
2001 Miami -17.33
2000 Oklahoma -16.47
2003 LSU -15.69
2004 USC -14.11
1995 Nebraska -13.74
2005 Texas -13.31
2006 Ohio St. (#2) -12.90
1999 Florida State -12.44
1998 Tennessee -12.22
2006 Florida -12.03
2005 USC (#2) -10.90[/pre]
On the whole, I think our 2005 team comes out looking pretty freakin great, not a big surprise maybe but I might have personally thought 01 Miami and 04 USC would have been slightly better than they did because I think even with Vince, we'ed have a very tough time with both in a head to head matchup. And while I knew our offense would kick butt, I'm pleasantly surprised that our Defense holds up very, very well in comparison.
