After Wisconsin manhandled Nebraska in the B10 championship (while being the third best team in the Leaders Div and only playing because of the PSU and OSU sanctions; I think it is safe to say that the Leaders Div is the strongest in the B10.
That being said, as the SEC seems weaker this year (even if the BCS formula tells you otherwise); where does the Leaders Div stack up against the SEC West and SEC East?
I think the top of the SEC West (Bama, LSU, and now TA&M) is still the dominant force and would win 60% of the time if playing OSU, PSU, or WIS; but outside of these teams, the Leaders Div is probably stronger.
I think it would be an even more difficult comparison between the SEC East and the Legends Div; although, top to bottom I would have to give it to the SEC East since they have 3 competitive ranked teams in GA, SCAR, and FL, and the Legends Div only has NEB and MICH.
If I had to compare these divisions; I would rank them as follows:
1. SEC West
2. Leaders Div
3. SEC East
4. Legends Div
