The Baltimore Ravens are calling in the big guns... to teach them how to swim? Legendary Olympic swimmer Michael Phelps says he will provide lessons to his hometown NFL team, which posted a plea for his help and claimed that a third of its players—around 17—never learned how to swim.

Michael Phelps is both the owner of 23 Olympic swimming gold medals and a Baltimore native and big Ravens fan, so he's the man some Ravens players appealed to when they wanted to learn to swim.

Michael Phelps may not be able to help his hometown NFL team on the field, but he plans to give them a hand in the pool. The 23-time Olympic gold medalist and Baltimore native has offered to help Ravens players learn how to swim at the team's new aquatics center.
