Chris Johnson expressed confusion over the Titans' signing of Shonn Greene.
The guy that tossed his offensive line under the bus a year ago now appears worried about his potential workload. "I have never been a big fan of the two-back system, so I don't know how we plan on using him," Johnson said. "I don't mind a guy getting a carry or two. But if I am the main guy and it is supposed to be my team ... it shouldn't be an issue." Johnson has averaged 349.7 total touches per season over the last four years. Expect that number to dip to around 300, with Greene handling the majority of short-yardage and goal-line work.
