RBs - Jahvid Best, James Starks, Shon Greene, Earnest Graham, Rashard Mendenhall

TE - Jimmy Graham
Given my roster, do you think it's a good idea to trade greene and flacco for tebow? The main reason I wanna switch flacco for tebow as my back-up is because week 9 when the lions have a bye, the ravens vs. Pittsburgh. Not 100% comfortable starting flacco even with the game they played against them earlier in the season.
