He’s the greatest swimmer of all-time, and arguably the greatest Olympic athlete we have ever seen, and he is retired, though many believe he could still bring home a few more medals, even a 19th gold. But Michael Phelps insists that he is finished with swimming. A month ago, a Florida news anchor reported Phelps was going to return to the pool to compete at the 2016 Games in Rio, but Phelps responded with a cryptic Tweet that certainly didn’t deny, but skirted the claim. Today, Phelps decided to just mess with us. While some say this was just part of a photoshoot with Speedo, Phelps sent out a picture on his Instagram account with the caption “One on one training session with @coach_bowman !!!” We think this is Phelps trolling people while making money from Speedo. He appears to have a pretty decent sense of humor. We believe that his training with Bob Bowman would have little to do with him working on his starts off the block. That being said, we aren’t certain that Phelps has completely walked away from the sport he has dominated for the past decade.
