Lot of sense, here.
With a defensive unit, it can sometimes only take one change out of the back four to make a difference. For us, that would be at left back. All this chatter such as "the entire back 4 need replacing" is, quite frankly, a bit daft.
Iorfa-Batth-Williamson-A new LB *should* be more than comfortable at this level. Hause & Stearman as cover in the middle is more than strong enough - both of those players would walk in to the starting 11's of a lot of Championship teams.
For me, sort left back out (don't be fooled by Doc's plus points going forward) and I think we'll look a lot stronger as a unit.
