I'd never looked at Gabriel Crews profile before, Willie. As a freshman at 310ish, he could develop into a pretty good nose tackle.
The more I look at our roster, the less screwed I feel when it comes to our defensive line. None of them will be the preffered size, but they're not going to get absolutely destroyed either. As long as they can hold their position long enough for the linebackers to get in there and make the tackle, we'll be fine.
The real question is how the 3-4 will defend against the spread. I don't know how well Ian Campbell would be able to cover Martin Rutger or Chase Coffman, for example.
