I really liked what I saw from MB. I often wondered why BP would take MB out for a good amount of time, especially when he had a head of steam going. As I remember, when JJ was playing this year, many on this forum were complaining that BP was using him wrong and different than he did last year. JJ didn't cross the 100 yard plateau this year which is what his backups are basically doing. MB could have easily surpassed 100 yards just like JJ had opportunities this year but we passed it up to pass the ball.
I'm not so sure that JJ would have faired much better than what you saw yesterday and I think that when he does come back, we may see more of the same that we were seeing before he got hurt.
Oh well, at least then we can blame BP for JJ's lack of production.
