But why would there be SA's when they were useless?
to spend more greens to get them ?

nay, I like some sa and have fun to have players with sa.
Anyway , even if you give let's say those 50-60 greens in quality instead of sa, nothing guarantees your victory.
In this last year, a team easily can loose from a -20% -30% opponent.
Unfortunately you can't buy Luck with greens

* btw dribbler is the worst sa after penalties specialist
and height is cosmetic.
