Since I am a bit late to the party (and not really good at these), this weekend I will go with all the home teams - which I know will not work out...
From the few games I have seen of the teams involved: Pittsburgh without Bell appears to make them one dimensional; Cincinnati appears to be playing better after that one Monday night curb stomping; Indianapolis's Luck appears to be a bit off these last few games and doing too much Catlering; Detroit admitted to everyone involved that without Donkey Kong stomping ankles and girders, they do not stand a chance; and Dallas's Romo is back in the playoffs and his history in these games.
I do not remember watching any Arizona, Baltimore, or Carolina games so in the dark about their perks or weaknesses.
Since Chicago is being a by-stander once again, I am neutral in the playoffs (and not one of those two, three, four team fans).
Good luck to those wanting their team to advance.
