You could end up having the DL and LB split between 3 coaches. Interior Line and DE, LEO and OLB and MLB.
TE split between OL and WR
I personally think Meyer is trying to get a DL coach because he either doesn't want to keep Fickell around for more than a year, or doesn't see Fickell staying around for more than a year. Personal opinion. With him bringing in Withers, who is a completely capable DC, it leads me to believe that more and more.
