You still don't have RBs, LJ might do good against teams like Denver or Atlanta or the Colts with horrible run defenses but put him against someone like Minnesota and I don't see him doing well. His O-Line isn't the same one that made him and Holmes fantasy beasts a few years ago.
Brandon Jacobs shares time with Bradshaw and Ward. Deuce McCallister has Reggie Bush and Piere (I know I spelled that wrong) Thomas in the backfield with him.
They are all capable of huge weeks, but not very good for consistency.
