WDIS: Fred Jackson or James Starks/Alex Green

Fred Jackson is only supposed to get roughly only 40% of the carries and it is raining in Buffalo. Also Jacksonville isn't very good. Packers play a good Vikings rush defense with backs that will more then likely split carries 50/50. No idea who to start. I know Fred Jackson statistically makes more sense but he's been injured and hasn't produced much since. James Starks has finally started showing up.... a little and Green is a bigger factor in the receiving game. any help?
