Tony Romo, as always, is a must start. Despite last week's poor performance, I still believe that Romo is an elite fantasy quarterback, and could end up being one of the five best fantasy quarterbacks in 2012. Unless you've got somebody like Tom Brady or Aaron Rodgers, you'd better be starting Romo.
Josh Freeman hasn't proven enough to me to warrant a fantasy start -- unless you're in a really deep league. Freeman is best left for the bench, or even the waiver wire, depending on your league. Sit Freeman.
DeMarco Murray, much like Romo, is a must start. Murray has RB1 potential each week, and at worst, is a very, very solid RB2 to start.
Doug Martin, meanwhile, is a decent RB2 option, and a very good flex play option. He's received at least 20 carries in each of Tampa Bay's first two games, and there's nothing to suggest that will change. Start Martin.
Another no-brainer on the Cowboys side, as Dez Bryant and Miles Austin are both must starts. Both have WR1 potential, and both are fringe WR1 / very good WR2 starts.
Kevin Ogletree, though, should be left on the bench for this week. There's no reason to expect a Week 1-esque outburst from him. Sit Ogletree.
Vincent Jackson is definitely a must start for the Buccaneers. No other Bucs wide receiver is worth starting.
I warned everybody to avoid Jason Witten in fantasy drafts, and so far, he's done little to prove me wrong. Witten has just six catches on the season for 68 yards. You've probably got better options at this point, but if you don't, you're forced to start him. Assuming you can find a younger, health tight end -- sit Witten.
Likewise, sit Dallas Clark.
