Huitama is, as a striker, at a point in her career that she must play. Better to get all the start in a lower league team then starting one of every 5 games in a top league team. That said some nWSL team would most probably beat some European team.
Huitama can return to Europe once she's 28-30 year old and a strong established striker.
She had to do the move to also secure her spot on the national team. I watched the u20 qualifying earlier this year and great players will knock on the door.
