It means if we need extra players we can send them foward and still have cover at the back. Also it would hopefully stop us conceeding the first goal which means we have to chase the game. It can change from 5-4-1 to a 4-5-1 by pushing either Durante, Dodd, or McKain foward. It can change to a 3-6-1 or a 3-4-3 by pushing the wide players foward also.
I realise it makes us look like a boring team with 5 at the back, but we can easily play attacking football by releasing players from the back.
