re: How big of a jump will LSU's defense really make in the upcoming year with new faces.

I don't care what improvements we see. You couldn't have what happened last year and not make a change. The only "unproven" coach is the DC. Everyone else has skins on the wall. And let's hope Raymond gets back to bringing in studs in the secondary. This was a huge improvement on paper. Which should translate to the onfield product.
