I know Peterson should be a must start, but he is playing against Chicago on Monday Night when they Bears could possibly clinch the division title (assuming Green Bay loses to new England). He is also playing with a low grade QB.
On the other hand I have Green-Ellis playing against the Packers in bad weather. This game could get out of hand quick which means lots of running to run the clock down. Jackson is my other RB and will get the start against KC.
So I'm thinking bench Peterson (which is a cardinal sin I know) for BGE because of the extremely unfavorable conditions Peterson has this week (including a minor injury and being listed as questionable).
