The Facts: Here’s a scary thought: McCaffrey has spent the offseason getting faster. The eighth pick of the 2017 draft, who last season fell 133 rushing yards shy of joining Roger Craig and Marshall Faulk as the only players in NFL history to top 1,000 yards receiving and rushing in the same season, also has gotten stronger. He has bulging biceps to show for it. “I’m way stronger than I was last year," McCaffrey said. “The faster I can get, the better as well. You can always get bigger, faster, stronger. I don’t have any choice. I have to."

Diehards Line: According to ESPN.com's David Newton, this transformation has come about thanks to a workout program that best resembles one for an elite track athlete and a nutritional program focused on increasing bulk and decreasing body fat. It’s different than anything McCaffrey has done previously, and the results recently were the topic of much social media conversation when this picture was posted. But the strength is only part of the story here. McCaffrey believes “you can never go wrong by being fast." He explained: “To me, speed kills. And the league is changing now, especially at the running back position, to where the faster you are, the more dynamic you are, not only with the ball in your hands, but running routes and being able to break tackles. That all has to do with speed. My position is a running back. So, the first part of my position is running. That means I need to run and be fast." And now he's faster than before. That's good.
