(But I'd take the 2004 team over this one no matter what)
This is an interesting thought.
Lets look a little further, to date this years team has played higher ranked opponents then the 2004 team did and records.
2010 opponents records 37-23
2004 opponents records 25-31
This years team in 8 games has already out rushed the 2004 teams total rushing yards for the season! a team with Ronnie and Carnel.
2010 Avg Scoring - 38.8 ppg
2004 Avg Scoring - 32.1 ppg
The 2004 team of course had the defense.
2004 Allowed 11.1 ppg
2010 allowed 23.5 ppg
I am not saying I agree or disagree with you, however I do know that I wouldn't say no matter what.
I do probably agree that the 2004 team would win (based on the defense of 2010) however, 2010 would score some points and I think the game would come down to a field goal. I certainly wouldn't want to bet on it.
