Open Extended ReactionsBALTIMORE -- Michael Phelps, the most decorated Olympian of all time, delivered on his promise to the Baltimore Ravens, teaching lessons in and out of the pool to his hometown team. Phelps, who won a record 23 gold medals in the Olympics, spoke to the team at the end of Tuesday's training camp practice before teaching some Ravens players how to swim. His visit came two weeks after cornerback Marlon Humphrey posted a video on social media, asking Phelps for his help because one out of three Ravens players can't swim. Earlier in the day, Phelps watched training camp practice alongside his son, Beckett, and Hall of Fame linebacker Ray Lewis. "It was a great day," Phelps said.
