For a team chasing its own championship dreams, Michael Phelps’ visit was more than a celebrity cameo. It served as an opportunity for the Ravens to absorb unique insight from a local legend who truly understands what it takes to sustain greatness over decades.

Olympian champion Michael Phelps has taken on the ambitious task of teaching the Baltimore Ravens football team how to swim.

In a social media video, Ravens Marlon Humphrey, Ronnie Stanley, Kyle Hamilton and Charlie Kolar invited Phelps, a Baltimore native and longtime Ravens fan, to visit their training camp. They said that one in three Ravens players could not swim.
