Chris Johnson isn't happy that he might have to share carries in the Tennessee Titans' backfield this season. The running back told The (Nashville) Tennessean that he was unsure why the Titans signed Shonn Greene in free agency. Johnson also said Greene's three-year, $10 million contract indicates he was signed to do more than just be used in short-yardage situations. "I have never been a big fan of the two-back system, so I don't know how we plan on using him," Johnson told the newspaper. "I'm not afraid of competition, but I was thinking we'd maybe get a draft pick for the other back. And you don't give a guy that kind of money to be just a goal-line guy and in tough-yardage situations. So we'll see what happens."
