Week 2 Quarterback Conundrum (Jameis issue)

Hey Footballers!

Entering week two I am working with Famous Jameis as my QB. I am in a 12-team 6 pt. per TD league, and most of the teams have two if not three QBs. I can pick up Keenum, Mariota, Fitzmagic, Minshew and Flacco. Do I start Jameis which is really ugly or do I go with one of the free agents? FYI I plan on doing some trades for a QB before week three starts.
