The lockout’s over. Preseason has begun. But the NFL’s legal troubles are far from over.

In late July, 75 former NFL players, sued the NFL, charging that the league has known for decades “that multiple blows to the head can lead to long-term brain injury, including memory loss, dementia, depression and (chronic traumatic encephalopathy) and its related symptoms,” and that it failed to warn or protect its athletes.

Last week, six former players and one current one filed a class action lawsuit against the league, the first of its kind. The suit accuses the NFL “of training players to hit with their heads, failing to properly treat them for concussions and trying to conceal for decades any links between football and brain injuries.”

The news of both suits comes on the heels of the February suicide of former safety Dave Duerson, who, convinced he had brain damage, donated his brain for study. He was right — his brain was ravaged by chronic traumatic encephalopathy, or CTE, a neurodegenerative disease often found in athletes who have experienced repetitive mild head trauma.

The trickle-down effect of all this has become increasingly prevalent in youth football. With evidence that even high school athletes can suffer brain damage, more than half of all states have either passed or have pending laws that address traumatic brain injury. Only seven states have yet to consider any type of youth concussion legislation.

Gov. Pat Quinn [D], who recently signed Illinois’ new law, said that “a lot of coaches are set in their ways. But you don’t want some kid you coached a decade from now with post-traumatic stress disorder or a brain disorder. You don’t want that on your conscience even though that boy or that girl wants to go in the game.”

But is football ready for this type of cultural shift? The idea is to prevent another Dave Duerson — but can you become a Dave Duerson, or have a championship team, while still staying safe?

Yes, according to researcher Tom Talavage, who authored a study [PDF] that found cognitive damage in high school football players NOT diagnosed with a concussion. His solution: hit properly and not as often. And he offers up an example:

We can still play the game, and we can still play the game at a high level. I think this is where the case of Saint John’s in Minnesota — we’re talking about a team that does not have contact practices, yet has won championships at its particular level of collegiate football. We don’t have to be a bad team just because we don’t practice. Instead, maybe we’re a better team. Maybe we focus more on technique, proper technique, proper blocking, proper tackling technique. Maybe we focus more on knowing exactly where we’re supposed to be on our play, what our blocking scheme is, what our defense scheme [is].
