Regarding the Wisconsin D, here are some comments from a Badger poster in another thread here.....
"The starting DEs for UW last year were Conor Sheehy and Alec James. Both of those guys graduated. The second string DEs were Chikwe Obasih and Isaiahh Loudermilk. Obasih graduated, while Loudermilk is just back from knee surgery. The third string DEs were Garrett Rand and Billy Hirschfeld. Rand tore his achilles over the summer and Hirschfeld quit football to pursue a career in journalism.
Basically UW only has one of their top 6 DEs from last year, and that one is still getting back into shape from surgery. The DE rotation currently consists of Loudermilk, a walk-on redshirt freshman in Matt Henningsen, and a redshirt freshman that was on the offensive line until fall camp in Kayden Lyles. Both Henningsen and Lyles need more seasoning in the weight room and on the field before they can be consistent run stuffers."
