We do have talent on the defensive line, it is just unproven. The hope is that they will be just as good as last year and maybe even better in the long run. Ty and Nash were great, but they were not All Americans. Heck, they weren't even all B1G. They can be replaced. Experience is what is lacking now. Hopefully, by the time the Michigan game comes to town the defensive line will have started to gel. The only reason I think this is the position group most to worry about is not because of a doubt about latent talent. It is based rather on the fact that a team can live with a weakness at Tight End, but it cannot be weak on either line and hope to be good. And our defensive line is still unproven.
