So far it looks like Purdue’s defense looks semi-decent, at least on paper. A different (and actually competent) scheme will play to its greatest strength at linebacker. There are a couple of solid tackles and at least some talent at defensive end. The back four, however, appears to be the weak link.
And really, it is only a weak link because there are a lot of questions. Purdue has a JuCo transfer and a graduate transfer, and a walk-on in line to play a lot of minutes. They aren’t really proven, but if they are the best options available then I trust this new coaching staff.
