Robert Griffin III didn't just run and pass the Washington Redskins to a victory over the Minnesota Vikings on Sunday. He also became the poster child for NFL player safety. Just a week before, Griffin was on the field face down after being hit by Atlanta Falcons linebacker Sean Weatherspoon. When team doctors discovered that the quarterback couldn't remember the quarter or the score, they diagnosed him with a concussion and forced him to leave the game. Griffin returned to practice after passing his concussion tests and was permitted to play in Week 6 when he was cleared by a team physician and an independent neurologist, as the league's rules require.
