But he's not sure that much more can be done to make the professional game safe.
"The protocol for concussions cannot be any more difficult to get back on the field," Rodgers said at a recent event moderated by Bob Costas, via the Milwaukee Journal-Sentinel. "It is incredible the process and the tests you have to go through to get back on the field.
"So something is being done. It's unfortunate that we've had to go through some years of learning what those steps look like, but I don't think there's a whole lot more that can be done."
NFL Commissioner Roger Goodell would likely disagree with Rodgers. The league is still looking for more that can be done. But Rodgers makes a good point that changes have taken place even in his short career.
"The helmet I started my career with in 2005 is no longer allowed because the safety requirements on those helmets is so high now. I feel confident the helmet I'm wearing has kept me from a couple concussions in the last year, especially one hit in particular I took in the Giants' playoff game," Rodgers said.
The NFL's legal battle with former players is not an easy problem to solve. The damage done to retired players of previous eras is hard to get a handle on.
Rodgers makes a fair point, though. For today's players, there may come a point when everything that can be done for player safety is done.
