FWIW, I'd hazard that the miniscule effect on flex/swingweight is outweighed by the fact that 1.5" less length is giving you more control and a better smash factor. Better control, better impact - all good.
I wonder what the record margin is for a World Cup victory? Thing is, the German players don't seem to do anything extravagant individually but they all do everything very, very well and they are the definition of a team. When one of them has the ball, so many are looking for space to take a pass. The running off the ball is so intelligent as well. It's not rocket science but they make it look effortless.
Indeed. Their support has got them this far in the face of some pretty poor performances. So many of their players are, basically, average. Certainly, when you look at the great players they've had so regularly in the past, who even gets close to that level? Neymar, maybe. But that's it.
