could to get on the field. i took injections. i took things for pain. i took anti-inflammatories really beyond the prescribed dose because i was in so much pain. it was really the pressure i put on myself. that's mainly what i saw, is guys wanting to play desperately. we're all obsessive compulsive, we're all high achievers, and you want to do anything you can't to get back on the field. >> well, that's one thing. but there are allegations the nfl and its doctors, its team doctors, rather, made it all too easy, in fact, encouraged players who are up against enormous pressures to cover up the pain and get back out there. some players say they were playing with broken legs, that they were playing with injuries that were only exacerbated because they were only taking pills and injexs and get back out there and playing. >> it's hard for me to imagine a person didn't know what their injury was, playing with broken legs. that was not my experience. in my experience, i sat down with the team doctors.
