Are you kidding me?
Nope not at all.
I honestly don't think that is a slight against Richardson by any means. Lets not forget that Blount has actually ran for over 1,000 yards in the NFL. He also has a very similar power running style to Richardson, he just isn't near as fast as Richardson.
But lets not act like Richardson is Barry Sanders or anything, he's not going to be juking too many people in the league. He doesn't have those kind of hips and honestly thats not really his style.
