McFadden is now a much faster man after working with Johnson last offseason.
How can that be when McFadden ran a 4.27 40-yard dash at the combine in 2008?
Well, did you notice that on those occasions that McFadden broke free early in his career, he was hawked from behind by an opposing defender that wasn't known for his speed.
He was even walked down by a linebacker in college.
Now a days, an opposing defender can forget about it once McFadden breaks free. That's because McFadden has increased his top end speed as the human body doesn't get to top speed until it reaches 40 yards.
The 40-yard dash is all acceleration or how fast you can get to top speed. The 20 meters after that is when the human body is at full throttle and that is where McFadden has improved under Johnson.
Another area that McFadden has improved under Johnson is his speed endurance or ability to hold top speed. After 60 meters, the human body slows down and your speed endurance determines the rate that you slow down.
McFadden's top end speed and speed endurance helped him lead the league in runs over 40 yards in 2010.
Notice that he doesn't get caught from behind anymore.
What will another offseason with Johnson do for McFadden?
