I just get an uneasy feeling when I read the excellent reports from the staff regarding the defensive line in particular, the team's primary concern this season. . Aside from the hope that the new schemes will work, Day is the only lineman consistently mentioned in the pass rush and the one lineman that ND can bank on. We know about Cage and Tillery , although Bryan was very strong in his statement that losing Jones was "major". Who else, if anyone, is seriously in the wings.
