Bush hasnt had a long scoring run yet, and peterson already has 5-6 of them. he brings power ( in which reggie doesnt have any) and also speed. i know that he has a solid offensive line, but they do not have any other offensive weapons to worry about. the defense is always keying in on peterson, and for bush, he also has brees and colston that defenses have to worry about, yet he still hasnt produced a long scoring run
