Rashad Jennings start/sit?

[teezy33]

Just swooped this guy up tonight (thank god for Christmas because on any other Saturday he would've been gone by then), and wondering what we can expect from him if MJD is OUT on Sunday. Right now my two RB's are Foster and BJGE - both are looking real good this week. Now, I would never bench Foster, but if Jennings is the feature back tomorrow at home against Washington, is he worth a start OVER BJGE at Buffalo? I figure he's at least a top 15 back but would anyone be courageous enough to call him top 10 for this week?
