Which QB do I pick up for Week 10?

Wow, tough choices, but I have been there before. Grossman or hill. I know Tennessee's defense is good, but Grossman has put up numbers in the past although he isn't super reliable. Wallace and seattle looked terrible last week and the seahawks are really beat up right now. I could see hill having a little success against Arizona, Arizona might get up by a lot and then San Fran can eat up yards and scores in garbage time
