This is a great move, IMO. Blount's running style is perfect for cold weather football and having the power running game to set up play action is what this offense does best. It's awesome what Gray did on Sunday, I thought he ran pretty well in the preseason as a couple of others have mentioned, but it's one game. If he can keep it up that's great, but if he can't, I really can't think of a better insurance option than LGB. Obviously Gray can't be expected to carry the ball 30+ times a game. Blount excelled in the system last year, so hopefully it doesn't take him long to get up to speed. With the o-line, Gronk and Develin playing like they are having a guy like Blount to finish games should be fun to watch.
