I have Neil Rackers(Arizona) whos playing Tenn and is listed as questionable because of groin injury,but it says he will most likely play. Or i have Billy Cundiff(Baltimore) whos playing Pittsburgh.
Given your choices, I'd start Cundiff against Baltimore. Tennessee has been playing very well of late and I don't think it's going to be as high scoring a game as the Pittburgh/Baltimore game as far as field goals go.
