Keep or Drop Harrison?

[Predator13]

Jerome Harrison has been very disappointing considering what he did during the last few games of last season. Do I hold onto him with the hopes things will improve, or do I dump him for one of the following lackluster RBs?

F. Taylor
P. Hillis
W. McGahee
M. Lynch
B. Green-Ellis

[Picksburgh]

Eh, if hes not starting you could take a risk. Taylor is interesting with Faulk out for the season, BJGE could be good if Taylor gets hurt. Lynch is also interesting as he is supposed to get the start this week and everyone is rumoring that he will be traded.
