FOXBOROUGH, Mass. -- On a steamy day in July 2015, Dion Lewis took the field under an angry sky in upstate New York. He was about to begin a workout on the University of Albany campus, not far from his childhood home, when the sun disappeared and it became "evil dark," his trainer, Mike Grasso, recalled. The wind kicked up, and soon there was a drenching downpour. Grasso looked at Lewis, waiting for him to call it a day.
"He didn't even blink," Grasso said.
The lightning-quick running back decided to defy the real lightning.
