Brett Greenwood is a former defensive back for the Iowa Hawkeyes whose life took a dramatic turn after he collapsed due to a heart arrhythmia during a workout in 2011, leading to severe brain injuries and a long recovery. Despite this, he made a remarkable return as honorary captain for the Iowa football team in 2015, inspiring many with his determination and resilience. His story has been honored through the establishment of a scholarship in his name and memorial tributes by the Big Ten Network on the anniversary of his triumphant return.
