That IS tough, because of the match up.
Romo played poorly last week because of a lot of dropped passes and the really bad offensive line. Field position also played a role, and it didn't help that the Dallas D let Marshawn Lynch get a few big runs on them. Too many big play IMO given up by the Dallas Def.
Brady also had to deal with a lot of drops, but that's life in football. This ain't pokemon, you can't catch em all. He also suffered from Hernandez getting injured...as did I (fantasy football-wise). I'm sure after the silly loss to the Cardinals at home (rigged IMO), they will finally play Welker more - although they did just pick up Kellen Winslow (almost 80 catches last year) and brought back Deion Branch. So they are still in it to win it. As for the Baltimore pass defense... Let me say this, the Baltimore defense has built a stigma around it that "It is VERY good" every year, although it is a stigma similar to how the Cowboys should be a playoff contender every year. Every year is different and with aging players in this speedy NFL today, my belief is that the Baltimore D is not as good as it used to be.
I would go with Brady. I am surprised you picked up Romo, but after New England's week 9 bye, I would try to sell Romo, or earlier is okay - as long as you can sell him high...viewtopic.php?t=521656
