You can get away with pushing everyone forward in non-league and league 2 football because teams generally don't have the quality, pace and power to exploit the gaps left at that level.
Already in League 1, there are only two teams that have conceded more goals than we have - and that may well be our downfall.
The problem is that it's the teams with the best defensive records that win titles and promotions - just look at the record books. Last season's premiership for example - the top 4 teams were in the top 5 defensive record group. Leicester, West Ham, Leeds and Spurs all scored more than Chelsea who finished fourth - but they conceded more and that was their downfall.
How they achieve that varies enormously and I'm not suggesting we abandon the way we play - after all if you have Superman and the Flash at CB and top athletes around them everyone else can go wander.
But we have wingbacks that go missing and Santos +1 at CB and whilst our style puts massive responsibility on them the better teams will be able to take advantage.
OK it's early days in the season but just like last season when Evatt had to switch from his preferred back 3 to a back 4 when we were getting battered every week, he may wish to rethink the system a little bit.
Of course any system change will impact elsewhere on the field unless you have incredible athletes who can effectively do two roles - but what do you think re our current squad? Tinker or stick?
