I was just thinking about this the other day.
IMO opinion, Frank is the best RB this team has ever seen. He's better than Craig. He's better than Hearst. He's better than Perry. He's better than Watters (by alot).
What sucks the most about this is the "Barry Sanders" syndrome. This team has never been able to actually take advantage of that fact and get it together. My fear is that by the time this team gets a real OC with a real HC and a real QB, Franks best days will be behind him.
I hope I'm wrong, but RBs don't last that long. :-(
