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.

Several Ravens – Ronnie Stanley, Kyle Hamilton, Charlie Kolar, and Marlon Humphrey – filmed a humorous video Tuesday, imploring Olympic swimmer and huge Ravens fan Michael Phelps, winner of 23 gold medals, to help teach players how to swim.
