they drafted edmunds, milano, bernard, and wiliams to replace and fill in for each other.
as much as mcd has his guys and is a loyal type, his history shows his d is about the line first and foremost, and he signed hardy who was a monster but a petulant man in carolina, and let norman walk. also, his d was hurt more there when hardy went down than when luke k was injured the one year, and people look at luke k like a hall of famer, and a super highly drafted MLB.
they let edumnds walk to a huge contract in chicago, and cut poy and tre white when they were too broke down to play.
the bottom line is i think this FO is a bit more ruthless on the defensive back end than they might seem, and if milano is hurt again, he's likely cut as soon as it is cap efficient to do so.
if he comes back this season, my expectation is he competes for the starting role and if he's actually healthy he makes a huge positive impact.
