Borland also conducted a question-and-answer segment following the documentary.

Borland will begin a 2½-month internship Tuesday with the mental health program at the Carter Center in Atlanta. His main focus since his retirement in March of 2015 has been to help former NFL players who weren’t aware of the risk they were taking — all while making much less money than today’s players.

He has volunteered with Gridiron Greats, an organization started by former NFL players Mike Ditka and Jerry Kramer that assists former players in need.

Borland, who hasn’t been involved much in changing the way football is played, said he believes the game “is about as safe as it can be.”

“I think the approach to making everything safer is brevity,” Borland said. “Waiting to play, hitting less often in practice and then shortening your pro career if you go into the pros. That said, we don’t know about causation exactly yet. There’s guys that have played for a long time and are totally healthy. There’s still a lot more to know and a lot more questions than there are answers, but my approach isn’t drastically changing the game. It’s just doing it less often will help the vast majority of football players.”

That means some major changes at the NCAA level, Borland said.
