IIRC '3-3-5' was a four letter word last year to the Michigan fan base/alumni and may have pressured RR into not promoting a D-coordinator from within his own defensive staff and sticking with the 3-3-5 Base D philosophy.
This year though...M hires Gerg and there is talk of a 'spinner', which then turned into "no, Stevie is a straight up SAM". Ok...so we basically took a DB and have him as a LB (3-4) but with the understanding he can cover the slot when need be (er...3-3-5?) Also, when asked what our base D is, instead of just always answering "we run a 3-4" we sometimes get "we run a 3-4" and other times get "we run a 3-3----shit, I mean...SCHEME DOESN'T MATTER, PLAYERS DO..."
Important to note...I DON'T CARE if we run 4-3, 3-4, 3-3-5...I'm sure RR's staff knows what is best for our base D. I just kinda found it interesting that it's possible RR, in a round-a-bout manner just installed a 3-3-5 Base D without pissing anybody off...
(Side Note: I still never head a reason why Graves and Dequinta Jones went elsewhere. Did they leave knowing a 3 man front would be the base D with whichever new D coordinator RR picked? Or they left for other reasons, leaving GERG to evaluate the talent and say...we gotta run a 3 man front...)
