I'm just going with my gutt, based on my experiences with this team. We usually get one or the other. Not often do we have both a good defense and a good offense.
We've had good defenses in the past, with below average offense. I just think now we'll finally get the offense we've been waiting for, but our defense will be horrific.
Shanny's teams have - for the most part - always had bad defenses. He picks some odd ones for D coordinators.
