One person isn't grassroots but I'd say that was more individual based and more free-market than this current issue.
It's still pussifying the league more though. Really, I mean to the players have to wear pink gloves too?
Bill Belichick learned to film signals of opponents from the former Chiefs, and Charger's coach Schottenheimer. Others like Edwards, Johnson and Cowher did too. They learned from the CHEATS and CHEATERS who still couldn't win.
