Their o-line isn't much better, but people seem to forget what Larry Johnson did last year when he played.
8 games. 745 total yards. 30 receptions. 4 total TD's.
So assuming he could do that for the other 8 games, Larry would have had just under 1,500 total yards and 8 TD's. Obviously not the stats that support his draft position last year, but those stats make him a great #2 RB option. The only thing I would worry about is if they over-use him, which could make him more prone to injury. But, I'd take the chance, especially in PPR leagues.
