is officially a retiree, so the Olympic legend suddenly has a lot of time on his hands. So the Baltimore native did what any red-blooded 27-year-old male would do - he stopped by the Ravens practice to hang out with the players on Monday.
According to BaltimoreRavens.com's Garrett Downing, the most decorated Olympic athlete of all time was invited by head coach John Harbaugh to talk with the team after practice.
What was Phelps' message to the players?
"Go get 'em," Harbaugh said. "He just talked about the last four years and what it takes to persevere like that."
Phelps, a die-hard Ravens fan, has credited linebacker Ray Lewis with helping him get his competitive juices flowing up to the London Games.
And Lewis knows a thing or two about firing up athletes. Back in March, the NFL star gaveto the Stanford basketball team (watch below). The laid-back Phelps likely can't match Lewis' fire but some players seemed awed by his presence. Said rookie kicker Justin Tucker: "It's pretty surreal."
