In theory, the position groups should go ...
Safeties - better with the addition of EMW
Corners - same
LB's - same (swapped 30 for 5)
IDL's - same
Edges - slightly worse, but, Verse may be the best edge in the division, as he's approaching the peak of his powers
DC - Rudy isn't changing the defense
So, safeties up, edges down (although I love Verse), and everything else holds.
I'm not sure how what equates to a bottom 5 defense
Of course, we won't know until we know
And, we all liked the Schwartz hire.
