The Baltimore Ravens are set to receive swimming lessons from arguably the greatest swimmer of all time. Ravens fan and Olympic legend Michael Phelps has agreed to teach Ravens players how to swim. The Ravens recently added a new recovery pool to their facility as a part of renovations to their Under Armour Performance Center.

Marlon Humphrey and other Ravens want to learn how to swim. Luckily for them, they landed the best teacher available: Michael Phelps.

Michael Phelps, the most decorated Olympian of all time, certainly knows a thing or two about swimming techniques.
