Well, our pick for last week was okay. . .not great, but okay. Chris Ivory got more carries for the New Orleans Saints last week against the Atlanta Falcons (15) than Pierre Thomas and Darren Sproles combined (8 for Thomas, 4 for Sproles), and managed 67 yards for his efforts. Not great, but a solid effort for a guy as a bye week replacement. He'll probably get worked more into the lineup for the Saints as the weeks progress, but that doesn't do you a whole lot of good this week.
No, this week, we're going to go with a guy at the wide receiver spot that could be able to help you against a fairly porous pass defense.
In the last two games, Cowboys' wide receiver Laurent Robinson has taken full advantage of an injury that has sidelined Miles Austin. He has five catches and a touchdown in each of his last two games, including a 70-yard touchdown catch against the Philadelphia Eagles a couple of weeks ago and a 6-yard scoring catch against the Seattle Seahawks last week. Austin is going to be out a couple more weeks, and Robinson will be getting the start across from Dez Bryant as a result.
The Bills' pass defense isn't very good, as they are allowing 260.4 passing yards a day, putting them 26th in the NFL in that category. Playing on the fast track of Jerryworld, it looks like something that Tony Romo can take advantage of, and it could be beneficial for you to pick up Robinson at this point.
According to Yahoo!, Robinson is currently owned in 44% of all their leagues, which means there's a chance he's available in yours, too. Go have a look and see if you could use an upgrade at wide receiver. Keep in mind, because of the strangeness of the NFL schedule, there are no byes this week, but you can always upgrade somewhere on your roster, I'm sure.
