It matters in the fact that we are trying to predict whether the Illinois defense will stay top notch or not on a message board. Illinois had 4 coaches, Bielema, Kane, Buh, and Walters who have D1 experience as DC's and now they have 3. We'll find out soon enough whether RW was a savant who masterminded everything or if an experienced coaching staff worked together and had a stud lockdown CB that made everything that much easier to gameplan around. I'd guess that with the Bielema track record that we'll be fine. If he could identify RW, why couldn't he identify the next guy?
I also root for the front of the jersey and not the back. So I don't plan on supporting RW at all. The goal is to be better than Purdue on game day and in the eye's of recruits. And in a zero sum game Illinois can only win at the expense of other teams, like Purdue, losing.
