Michael Phelps casts such a gigantic shadow that training in it can be a bit chilly.
Not that Phelps isn't genuinely supportive of his training partners at Arizona State and his previous home at the North Baltimore Aquatic Club. He and six-time Olympic medalist Allison Schmitt are as close as any brother and sister, and Chase Kalisz is like the brother he never had growing up with his mother and two sisters after his parents divorced.
It's just that Phelps, whose 18 Olympic gold swim medals give him twice as many as anyone in any sport, soaks up almost all the attention as he works toward his fifth Olympics at age 30.
