I think Emmit's injury will have a definite positive effect on the Arizona offense. Their OL looked awesome last season and Shipp put up good numbers down the stretch. I see him as a minny Jamal Lewis, a good combination of power and speed.
Does anyone know if the Az OL is the same this year? Did they lose anyone? If not, I'll assume that the running game has tanked it mainly because they decided to play a 243 year old RB. As for Boston leaving, Az ran well with Boston out last season so I don't see that as having a major effect.
