I'd go with Young but I wouldn't like it. Don't be surprised if the whole Jets D thing is a little overblown or Revis is a little rusty, etc. and Flacco puts up a decent game. For what it's worth, I'm playing D. Anderson over Flacco, but I don't like it either.
If your QB doesnt get points for handing the ball off, you have to go with Flacco. He has a new to this year and another year of experience. Revis has to be rusty.
