Let's keep this simple. Romo has the upside except for PPR. Maybe. At home with all weapons loaded, Murray could be big out of the backfield with xtra receptions. I want to say Brady as my TE is Gronkowski. However, sacks and int's may be relevant. Romo can scramble, Brady, not so much. If you believe that that the Pats cannot loose two in a row, so be it.
As far as the RB situation, I stopped following closely any Wash. RB so far this year. Though, I must say, with your lead, Martin will not lose your week.
