Nobody is talking about individual teams; the discussion is about the greater dynasty, the greater amount of success over a period of several seasons.
And included in that period of several seasons is the greatest team of all time. Has to be in the discussion.
The gap between the greatest team of all time and one of the greatest teams of all time (2009 'Bama) is a lot smaller than the gap between "National Championship" and "No National Championship".
Yea, and we got hosed out of the 1993 Championship. So there's that. 4 undefeated regular seasons to 1.
Again. I hear what you're saying. We have accomplished things that Alabama hasn't. And they are legitimate. But if they win a 4th title, I mean just do a simple comparison of the five year stretches:
Nebraska 1993-1997
3 National Championships
1 Lost National Championship
4 Conference Championships
1 Lost Conference Championship (From playing in a championship game)
4 Undefeated Regular Seasons
3 Undefeated Seasons
Wins over (at the time), #20, #16, #24, #13, #16, #2, #3, #8, #7, #10, #2, #5, #10, #2, #17, #14, #3 teams.
Losses to (at the time), #1, #17, unranked teams.
60 wins, 3 losses (95% win percentage)
Alabama 2009-2013
4 National Championships (0 lost)
3 Conference Championships (Assuming they would win in 2013)
1, possibly two undefeated regular seasons and seasons
Wins over (at the time) #7, #20, #22, #9, #1, #2, #18, #10, #7, #17, #7, #23, #14, #12, #1, #8, #13, #5, #3, #1 teams
Losses to (at the time) #19, #10, #2, #1, #15 teams
63 wins, 5 losses (assuming undefeated season) (93% win percentage)
Not saying it's definitive either way, only saying that when all other things are equal, or even remotely close to equal, an extra championship is a remarkably weighty addition.
