OT: Week 16 Fantasy Start/Sit

Championship week right?  Somehow I find myself contending. 

Larry Fitzgerald, Jermaine Kearse, Ruben Randle, Kamar Aiken - pick two of these four please.  Fitz has been a dud with Brown back, Baldwin looks to be a game time decision (though Rappaport says he'll likely play, in addition to Oakland still being in play), Aiken is going to die with Mallett at QB and no other offensive threats, and Randle is tough to start but he's the clear #1 WR with Beckham sitting.  I'm also tempted to go big or go home with Keyshawn Martin - LeFell will get Revis'd and someone else is going to have to catch a pass besides Gronk with Amendola (and Edelman) out. 

I think I go with Fitz, would like some advice on the other. 

And I have both the Steelers and the Cheifs defense.  KC at home against Cleveland would typically be a no brainer, but don't I have to start the Steelers vs. the Ravens with Mallett at QB?  

Good luck to all today.
