He's missed a game or two, I believe. He's not really most valuable to his team... They have two other backs he shares time with. I'd give MVP to Eli before Jacobs...I put Kurt Warner. I personally think that he has Kept this team alive, especially when he was in contention during the Pre-Season with QB Matt Leinart.
He's been phenomenal this season, hitting not just 1, not 2, but 3 receivers so many times for so much yardage, that all 3 of them (Fitzgerald, Boldin, and Breaston) have a great shot at 1k yards. Fitz already has it. In 3 less games, Boldin has i believe somewhere aroundthe high 900's and Breaston is I believe somewhere around 750-850. Not many QB's can pull that off.
Also (not no list) but I wouldn't sell Brandon Jacobs short. Great yardage, hasnt been getting injured, has incredible speed for his size, uses his size towards his advantage, and has a great yardage/carry this year. He's also joins a few others at the top of the list for most rushing TD's this season.
