For 49ers’ Brock Purdy, speedy processing skills started with flag football (paywall)
“Like a lot of parents, Shawn and Carrie Purdy had some safety concerns about tackle football when their boys were young. More than that, Shawn said, was the speed of youth tackle football. It moved so slowly that he didn’t think it would benefit his sons and that they wouldn’t have as much fun.
He said he remembers Brock’s friends teasing him about playing a game in which you try to strip flags from an opponent instead of trying to take him to the ground.
