The inability to wear down opponents in the 4th quarter this year and last year as well is a bit concerning. Although it was not flashy offensive football we were able to dominate in the 4th quarter with power football a great deal this decade. We were the bullies of the big ten. I feel a bit of this is lost. This was especially evident against Penn State and Wisconsin this year. They pulled an " Iowa" on us. It makes me wonder if our strength and conditioning is a bit down, if other programs are catching up or is it just a personnel issue. Thoughts?
