I agree, there have been many players at multiple levels who have made changes in position. My guess they wanted to play on the team or the head coach approach and suggested to try this position...since, there is a opening.
1. Klingenberg-UNC attacking mid, US WNT-wingback
2. Solo-Club team forward, college/US WNT-GK
3. Dunn- can play wingback or forward. Played both as a Pro and US WNY.
4. Heather O'Reilly- Stanford forward, US WNT- wingback
5. Lauren Chaney- UCLA forward, US WNT- holding mid
6. T.M.- USC incoming freshmen, plays forward at club and plays centerback for U19 YNT
7. Refer to the Stanford incoming freshmen mentioned earlier
8. Gorloski- UCLA player, played forward in club, at UCLA-wingback
9. Cerda-UCLA player, played forward in club, at UCLA-wingback
The list can go on and on.
