If you do NOT lose points for sacks, I'd start Kitna. I'd be surprised to see NO put up more than 20 on Tampa, can't really say the same about Detroit. They will most likely be forced to pass because Minny's run D is so good. However Kitna's numbers against them earlier this year were horrible. Still, Kitna.
As for RB, clearly it's just worth waiting till gametime, but I'd honestly lean toward Selvin Young just because Henry hasn't played in 3 weeks? Something like that. He will be rusty. Henry will probably start but Young will probably get the carries that count.
