That's where a guy like Charles Roberts just thrived. He knew instinctively where to go to find space and he had the quickness to change direction and throw would be tacklers off that way. Grigsby just does none of that. Oh sure give him space he can be fine, but I'd rather look for a runningback who can make something out of nothing because we're not getting a new offensive line any time soon.
even in space, he made a nice cutback against sask, had one defender to beat in space and couldn't do it.
