Armour: It's time for Michael Phelps to grow up Nancy Armour, USA TODAY Sports 2:45 p.m. EDT September 30, 2014 (Photo: Rob Schumacher, USA TODAY Sports) 1 COMMENTEMAIL There are absolutely no excuses for Michael Phelps this time. None. The Olympic champion swimmer was busted for DUI early Tuesday, appearing "to be under the influence" and failing a series of sobriety tests after police spotted him doing 84 in a 45-mph zone. Mind you, this comes 10 years after he told a judge that he recognized "the seriousness of this mistake" while being sentenced on his first DUI-related charge. USATODAY Michael Phelps arrested on DUI charge Phelps was 19 then, and nowhere near the global celebrity he is now. Not that there's ever an excuse for driving while impaired, but teenagers do many stupid things. Most, however, learn from them. Not Phelps. He's 29 now, old enough to know better. He's also got enough money to hire a different driver for every day of the week. Yet he still climbed behind the wheel of his Land Rover. He's fortunate the only charges he's facing are traffic-related ones, not something like vehicular manslaughter. There is no question Phelps is the greatest swimmer of all time. Probably the greatest Olympian, too, with a record 22 medals, 18 of them gold. But that doesn't make him invincible or beyond the law. Someone, be it his mother, coach Bob Bowman, USA Swimming or one of the sponsors that pays him so handsomely, needs to sit Phelps down and tell him to smarten up. To grow up. If he wants to go out and party, that's his business. But give the keys to someone else.
