In the US, the talent pool of female soccer players is only so deep and with over a hundred college schools going after the quality players, mid-major teams are lucky to get 3rd or 4th pick of them if that.
Now, the pool of quality foreign players is not as deep but the talent level is increasing with them.
Having a soccer coach of Rafa's background and talent of recruiting under Coach Grassie, he's a good judge of talent and can recruit foreign players already here in the US as well as going overseas to reel in the ones missed in those locations.
