Bolt has the height and speed to be a deep threat for someone like Robert Griffin III or Joe Flacco, who have taken a liking to tossing up jump balls. However, he doesn't have the body, or the experience with the physicality in the league, to withstand hits across the middle. It's easier to outpace Justin Gatlin for 10 seconds than to deal with Richard Sherman and Kam Chancellor for 40 snaps per game, and even Bolt recognizes that.
