The One Love Foundation was established in 2010 in memory of Yeardley Love, a University of Virginia lacrosse player killed by her ex-boyfriend, a fellow athlete on the men's lax team there. Two years ago the foundation debuted a 38-minute dramatic film called Escalation to a group of baseball and men's lacrosse players at Jacksonville University. The eye-opening film, which teaches about the warning signs of relationship violence and is paired with a discussion led by trained student facilitators, has made a real impact. To date, 85,000 have seen it, and the workshop is required for student-athletes in 61 colleges and universities, including Duke, Syracuse and Berkeley. Maddie Stuzin, a sophomore on the Columbia lacrosse team, brought the program to her school. "To see it spread across the country is amazing," she says.
