Half the squad being replaced, in my opinion, is a bit over the top.
We all know defensively we need improvements but I dont think its a drastic as some think. Kiernan & WIlson are both decent centre halves but they are too similar and in recent weeks they have struggled to play together. I think we need a quick ball playing centre half to play alongside one of them. That would compliment the partnership better than having 2 old fashioned types trying to play the MW wants us to.
