MLB needs both z/m2m. OLB need higher br/c, m2m vs zone.
Then again, is one running more m2m (much more viable in 4.5 as zone STILL has issues *hoping 4.6) over zone in the LB D? Right now, MLB needs both in equality (+70) and OLBs need more m2m/br/c.
There are position weights/clues available for 4.5 within the forum search.
