Dronett was drafted in the second round by the Denver Broncos in 1992 and played four seasons here, racking up 21 sacks, before joining former Broncos coach Dan Reeves in Atlanta. His career ended in 2006 after a series of knee injuries.
In the story CNN's medical reporter, Sanjay Gupta, reports on Dronett's "transformation from an affable prankster, quick to flash a wry smile, to a person who was often frightened -- and frightening..."
