Yes he is our MIP
No he shouldnt be our starter. He is too small and would take a beating in the backfield. Additionally, his two assets are kick returns (which he is a pro bowler in that position IMO) and situational back. Using him as a starter and a kick returner would diminish his #1 responsibility on the team. Same reason why Sproles is not the every down back in SD. Too small and the beating he would take on his small frame would put him out 5 games into the season.
Backs like Timmy and Beanie are built physically to be starters. The problem really isnt with the RBs themselves, but rather the sub par run blocking. Ive said this many times but neither can get to the 2nd level because holes either never develop or close up in a New York minute. Watch our run blocking and watch that of the Jets. World of difference. You could drive a Mack truck through any of the holes the linemen for the Jets make for their backs; while with ours, you couldnt fit a piece of tissue paper. Also, a good fullback would help the cause. Maui'a is not the answer. He lacks awareness of his assignment and whiffs on blocks way too many times.
