Why would a club having two zone league teams be a problem?
Having a ZPL side & a ZL2 or 3 side means you could put all your younger players coming through into ZL3 & bring them up into ZPL in a few years once developed. Or even chuck the older guys that are past their prime in the lower side..& also they can mentor the younger guys? Not every kid coming through is good enough for NPL.
you cut B teams & I’ll tell you now we will lose players to the game all together fast.
