BO is good- granted. I think he was also the benefactor of an offense designed around him, a commitment to running the ball and an Oline that has a powerful run aspect to it. I think you put Stanback, Brown or Karey in that offence, I feel any one of them would have churned out more yard from scrimmage.
Now factor in the savings- either one of those three, probably could be had for less than $150k- a savings of ~$90k. That is a good chunk of change for other areas of need.
Also, I think Stanback would have been a really good fit here- I think his running style fits the Bombers Identity best.
I do like the hometown hearo story line and he is genuinely a good egg. BUt if its team first- I think flipping the rb to import would be the way to go. Just my opinion.
