Good move for the 2010 season.
A healthy Cates, parlayed with a healthy O-line and new OC will hopefully equate to some much needed creativity and added yardage to the run game.
The cohesion between Durant and Cates can only help towards THIS YEARS Grey Cup push.,. Come 2011 though I expect some large changes to the offense.
IMO. Adding Cates indicates Dorsey will not platoon as HB, but will be a full time returner - making Armstead expendable....unfortunately.
