The modern NFL doesn’t really demand “Super Star” running backs. Nowadays, most modern offenses require backs who can do a lot of things well, but don’t necessarily need them to be exceptional in any one area. Having a runner who can do what is asked of him regardless of the situation is the current mold for an NFL running back.
That pretty neatly sums up Michigan’s Hassan Haskins. Haskins has good size, good athleticism, and a well-rounded skill set, but he isn’t truly “elite” in any one area of his game. Instead, he’s greater than the sum of his parts and was able to do whatever Michigan needed him to do.
