I know it's semantics, but when was it ever 5 at the back against Brizzle. It was 3 at the back with two outside pushing forward. I don't recall Frazer ever defending (except when he kept them onside for their 2nd) and Welington didn't do much in the way of defending.
The big problem I have with what Still says about getting it forward being the key, not the formation, is that is exactly what our defenders (whether its 3, 4 or 5) don't do. They pass it around at the back and always look to play sideways or back without trying to get it forward, just like in Martin's time. The only difference I see is that McCarthy does sometimes launch it. THB is the worst at playing it around at the back, except occassionally he seems to remember to try to get it forward and alunches a diagonal to no one. I know its heresy on here but I think Jack does a better job of getting it forward than THB.
