Russell Wilson...Do I start him?!?

I am headed into the second week of the first round of the playoffs. Currently I am up 30 points. I have Wilson starting, but I am a little worried. Should I stay with Russell or should I stream one of the FF options? Winston, McCown, Carr are all on the waiver wire.

Another question is do I start Perine or Freeman this week as my RB2? This is in the same league which is full ppr.

All advice is welcome and appreciated…Thanks FC
