It's not hard to do, no. And if I'm being fair, then I'd say Rodgers could do it if we tried, but Rodgers is trying to instil a hybrid counter-attacking game, with the onus on being offensive rather than defensive.
My issue with that, and with Rodgers' system more specifically is that it absolutely is possible to be a team with positive, attacking intent that take the game on and be solid defensively. Rodgers attitude that 'you can teach anyone to put 11 men behind the ball' is correct, but you can also teach anyone to go out attacking recklessly without care for defence either. There's a fucking balance that has to be found, and can be found. Adopting that attitude doesn't endow you with the status of being avant garde, it just highlights your naivety really.
His disregard for full-backs that can defend, his disregard for a disciplined defensive line, his disregard for team structure when holding onto a lead, and his evident preference for a DM to be a ball-playing DM rather than a foil for the defence behind him leads me to believe he either can't coach that area effectively, or doesn't want to. Both of which are frightening.
I think I've said this before somewhere but I would dearly love to watch how he coaches the players during the week, and what he does in training. Let me tell you, one of the most dangerous sayings ever promoted in modern-day football is 'we do everything with the ball at training'. It's a fucking myth.
Good defences, good training methods, and good defensive coaches attribute the time necessary to educating players and teams how to defend. And large parts of that are down to just getting players to know how the system works and where they should be. I remember being taught how to defend zonally from corners 15 years ago. There wasn't a fucking ball in sight. Fuck the ball off, and work on positioning and systems.
I don't blame Lovren, or Glen Johnson, or Coates, or whomever. I blame the system, and the man who should be responsible for it.
Defending's a lost art apparently, and disregarding it like we have for the last 3 odd years has gotten us exactly what we deserve.
