Help with QB, RB's and WR's?

Ok first week of playoffs, its a big game. For QB's I have Donovan McNabb vs Cle and Brett Favre vs Buffalo. Which one would you start and why? RB's I have Marshawn Lynch vs the NYJ, Steve Slaton vs Ten and Frank Gore vs Mia, which two would you start and why? WR's a bit easier but I thought I'd ask, I have TO, Randy, Andre Johnson and Marques Colsten, which 3 and why. This is a none PPR league. Best answer gets 10 pts and thx in advance!
