When Washington quarterback Robert Griffin III stepped on the field for the first time since blowing out his knee in January he looked like a guy whose recovery is still a work in progress rather than a player who is all the way back. That’s the word from former NFL quarterback Ron Jaworski who said on ESPN’s NFL Matchup that Griffin isn’t throwing the ball well because he’s still favoring his injured knee. “His mechanics are flawed right now because of the injury” Jaworski said. As Jaworski showed a Griffin interception he talked about how Griffin’s footwork was all wrong. “He never gets his weight on the back foot. As this ball comes out it’s going to lack energy” Jaworski said. “His front foot which is where your weight should transfer to actually pulls back. So you’re losing the body momentum the ability to drive the ball with the hip snap to get the ball to the outside.”
