Ashley is really 5’3” (5’4” with cleats) and probably 115 lbs. What many don’t know is Ashley is very very strong for her size. I recall she already had a six pack when she was 10 years old.
I agree a smaller player needs to be at a minimum 110 lbs and quick. IMO, what is more important for a smaller player is they need to have a low center of gravity...so they are not knocked of the ball and play in a possession oriented system. It’s why the smaller rostered players at UCLA and Flordia are successful, because of their possession oriented play.
I know it's common in the US to judge soccer players by body types, but I think it is a big mistake. This is not a one size fits all sport. It's a sport made for... well... those who are good at soccer... regardless of body type.
There is a dancer-like agility quotient to this sport which is what makes it "the beautiful game" in the rest of the world-- and I think that is often neglected here.
