Career Highlights: O'Hara was a forward during her collegiate career at Stanford, scoring 57 goals to rank second all-time for the Cardinal and winning the 2009 Hermann Trophy. After that, she converted into a defender with offensive capabilities. Her ability to play forward has lent well to her development as one of the top young defenders for the U.S. She'll be used at wide defensive positions and in the midfield at times, and her strong ability and comfort on the ball make her a major threat out of the back. Those are major plusses for any team, but the U.S. now has another option to use when trying to transition offensively. O'Hara has seen increased playing time this year and may be a regular in the starting lineup by the time the London Games kick off. She was on the team for last summer's World Cup but only appeared once as a substitute. While her position isn't considered one of the more glamorous in soccer, she may end up becoming a star due to her ability to run at opponents with the ball.
