Cornerback Marlon Humphrey posted a video on social media asking 23-time Olympic swimming champion Michael Phelps — a Baltimore native — for swimming lessons. The video includes Humphrey, tackle Ronnie Stanley, safety Kyle Hamilton and tight end Charlie Kolar standing in the pool.

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

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.
