Hall of Fame quarterback Brett Favre is likely one of the football mad men on the planet.
The former Packers star dedicated his life to the game he loves, and achieved an incredible amount in his 20-year NFL career.
Favre won a Super Bowl, three MVP's and earned 11 Pro Bowl selections amidst one of the most glittering careers in league history.
However, his storied history in the game isn't preventing him from proposing some changes to it's grass roots rules that are certainly stirring some strong opinions from around the football world.
The changes are in the name of player safety at a young age, but that still draws a seething reaction from many purists of the game who believe it is sacrilegious to remove key elements of the sport.
Favre wants to end tackling in youth football for good.
'I think it's going to take someone who has poured his blood, sweat and tears into it,' the 48-year-old told the Daily Mail.
As the prominence of CTE in NFL players continues to rise, Favre is all to aware of the long term consequences of concussions and he wants to be remembered as someone who put the safety of kids first.
The former Super Bowl champion estimated he suffered 'thousands' of concussions in his career, and he's adamant that removing tackling from the youth game will significantly improve player safety, even if it's entirely unpopular to begin with.
Favre is currently supporting a proposed Illinois bill forbidding anyone under 12 from playing tackle football.
'The state level is a start, but we have to adopt this plan and all do it together,' he said. 'The body, the brain, the skull is not developed in your teens and single digits. I cringe. I see these little kids get tackled and the helmet is bigger than everything else on the kid combined. They look like they're going to break in half.'
Participation in youth tackle football dropped by a staggering 19% between 2011 and 2016, and Favre is again supportive of parents taking their kids out of the sport whilst it remains dangerous to their long term health.
'I think the reason for that is that parents are steering their kids away from tackle football to something a little bit safer,' he said.
Favre won't even let his own son play football in the back yard, that's how concerned he is about the damaging effects of the game on the human body.
'Maybe that's selfish,' Favre said. 'But what are the odds of him becoming the next Brett Favre? What if he plays one year, gets a major concussion, and is never the same.
'I would feel horrible.'
