Detroit Lions defensive coordinator Gunther Cunningham has said that quarterbacks who run the read-option offense will sustain more injuries.
Cunningham told the Lions' official website: "The problem is for those quarterbacks, one of these days, one of them is not going to walk off. It's a lot of pressure on him to physically do that.
"I think we all understand what the issues are and how to play it. I reflect back on my college days and it wasn't that hard to remember all that stuff because it put a lot of pressure on me in those days and it does in this league, too."
Griffin was named NFL offensive rookie of the season in 2012, having used the read-option to guide the Washington Redskins to the playoffs.
