A thing to bear in mind is this is a simulation and it seems to work on the principle of a 'player event' = using a skill set. That's basicly all players use there P&M skill set and choose from either Def or Att each time.

The effect of this can be seen in particular with arrows.......if you put a blue arrow on a player you're encouraging him to be more Phys& Mental and More Def.......so if its an MC and he has low def its 'not optimal'. Same for red arrows....if you put a red arrow on a DR because ypou want him to link and pass down the flank but he's all def statted then its not optimal either.

So all players should have good physical stats imo.
