Jason Whitlock has an interesting take on Robert Griffin III and the impressive 40-time he displayed at the combine.

In my opinion, Griffin’s speed doesn’t enhance his draft stock. It damages it.

I am not a Robert Griffin hater. I love RG3. In all likelihood, he will be my favorite NFL player next season. He could quickly become my favorite active athlete, ahead of Tiger Woods, Ray Lewis and Jeff George (has yet to file his retirement paperwork).

But I’m worried about Griffin. He’s blessed with too many tools. Oftentimes, the greatest athletes are physically limited, which strengthens their focus. Bill Russell could never match Wilt Chamberlain’s size and limitless athleticism. Larry Bird and Magic Johnson weren’t the greatest leapers or the quickest on their feet.

Tom Brady and Peyton Manning are relatively immobile. They play from the pocket because they have no choice. They mastered the art of playing from the pocket because they had no other choice.

NFL games are won most consistently by quarterbacks who play from the pocket. If a quarterback leaves the pocket, he’s going to get hit. If a quarterback gets hit regularly, he’s going to get hurt. If a franchise quarterback gets injured, his team has little chance of winning the Super Bowl.

NFL teams are looking for the next Manning or Brady. Or the next Eli Manning, Aaron Rodgers and Ben Roethlisberger. A little mobility is good, especially if the quarterback moves in the pocket in an effort to throw downfield. Rodgers and Big Ben are terrific at moving to throw. Is that how Griffin will use his athleticism?

Or does Griffin have so much speed that he’ll channel Michael Vick?

Whitlock goes on to recount Vick’s early problems as he relied too much on his speed and athleticism. Athletes like Steve Young had to learn how to stay in the pocket.

Whitlock basically sums up the primary reason why Andrew Luck is rated higher than RG3, even as some think RG3 has more upside. It’s a risk/reward analysis. Luck has shown that he can win strictly as a pocket passer, using his athleticism only when needed.

Can RG3 learn to play that way? Of course he can. But just because he has the aptitude and temperament to learn doesn’t guarantee success. Luck isn’t guaranteed success either, but we’ve seen him operate consistently from the pocket, so there’s less risk.
