USA TODAY Sports Olympics reporter Rachel Axon catches up with American men's gymnast Jake Dalton, a four-time world medalist and hopeful for the 2016 Summer Games. Eight months removed from shoulder surgery, Dalton talks about his path to rebounding for Rio, the strong mix of contenders on the United States team and his mostly strict nutritional regimen. And, as a San Francisco 49ers fan, Dalton weighs in on Chip Kelly, Colin Kaepernick and what's to expect for the Niners.
