Double QB League Alex vs Trevor

Must Win- Double QB League- Got Cam, Alex smith, And Trevor Siamiain. Could pick up Jimmy G off waiver. Cam is a definite go for me.

I have been doubting Alex smith abilities lately. After 2 poorly favorable match ups. Im thinking i cant count on him. Back to old Alex smith. I picked up Trevor for this week to possibly play over Alex smith. Before you say smith for sure. Think Alex smith a little shakey now against New york jets which has been giving teams a hard time kind of. Or Trevor against a Miami who like to give it to QB.

Would i be crazy to start Trevor over Alex?
