Some truth, No i dont think either of the Rams back up QBs could do what he is doing...but as we all know the Rams back up QBs are not NFL level talent...when given a chance they failed. Perkins not as much because McVay refused to let him throw...but Wolford stinks and he would likely do a bit better with the Niners and their ground and pound game plan then 5 step drops and roll outs.
Yes I think the Niners system is really solid, with the right peices the Rams have proven what their system can do.
