He knows of what he speaks. Steve Young was great on his feet, but he never rushed for more than 75 rushing attempts in a season in a 15 year career. RG3 had 120 rushing attempts in his first season, and that's with missing about 1.5 games and being limited about a quarter of the season. It's not just some fluke that RG3 was beat up to hell by the end of the year. There's a reason why no one in the NFL has implemented the option as their base package. He's not a large framed guy to boot. It wouldn't be insignificant if he needs a surgery to his knee that knocks him out the offseason. He's got a lot of things he needs to work on. NFL Defensive coordinators are going to adjust to the pistol concepts, and RG3 will need to expand his dropback game to counter to the adjustments.
