We start two QB's....right now I have five....RIvers, Cassel, Garrard, Favre, and Leftwich. I have been offered Stephen Jackson for Rivers......I would use Jackson as a flex, as I already have Turner and C.Johnson at RB.
I am afraid of Jackson's injury history, and the fact the St. Louis offense sucks so far......but I could fill the QB spots with two of the other four, and upgrade at flex with Jackson.....help.
Don't give your opponent Rivers unless he already has depth at QB, otherwise you are giving him a gift. I think Jackson is good to have at this point, the Rams have no passing game or O-line, they will be relying on Jackson more.
