NFL protecting its Golden Boy Griffin

Based on the calls made by the refs during Sunday's game, the NFL is doing its best to protect its Golden Boy, Washington Redskins quarterback Robert Griffin. A few questionable roughing calls against the Minnesota Vikings' defense means the NFL badly wants Griffin to succeed, as a successful black quarterback is important to marketing the game. Let's be honest though, what's the point if he can't be successful on his own?  He's certainly way better than Michael Vick ever was, or is. I'm not sure why the league would want or need to protect him. Guys get injured in football even when they don't get hit, so why worry about it? Just let him, and the defense, play the game.
