CLEVELAND -- One of the biggest names in football is making some of the biggest waves in awhile.

"When you start forgettin' things that are so obvious, that should be so easy to remember -- that' s-- that's scary," veteran quarterback Brett Favre tells NBC News. Asked if he had a son, would he let him play, Favre said: "I would be real leery of him playing. In some respects. I'm glad I don't have a son because of the pressures he would face."

These comments come the same week the nation's leading youth football program reported a 9.5 percent drop in the number of kids participating in their leagues compared to 2010. The league's director tells NBC News: "There is no hard data that links participation numbers with fear of concussions."

"People are scared to let their kids play," says Glenville High School fan Rodney Washington. His son is itching to play in a few years. "When I played ball, they didn't know what they know now, about concussions."

Just this week came word of a Missouri high school player who died two weeks after suffering a brain injury, while in Atlanta a player died after breaking his neck in a preseason scrimmage.
