Jonathan Wells was a great playmaker running back when he played for the Buckeyes! I was a fan watching him run for multiple touchdowns against Michigan.
When he played for Houston, he never had much of a playing opportunity because of Dominack Davis. When he played in spot duty he played above average. He beefed up to be fullback, but is planning to take the weight off and play tailback again.
I think that he would be a great pick-up and I hope the Bills sign him. In time, would take Shaud William's spot as the #2.
By the way... this cements the fact that the Texans will take Reggie Bush. If they were targeting someone else, they would have kept him.
