I'm really not on the Domanick Davis wagon. The guy just isn't getting it done this year. 2.8 ypc is horrid, and it doesn't look like he's going to break out of the funk anytime soon. I'd actually hang on to Duce Staley, unless you get a great deal for him. He's putting up stellar rushing number, minus the TD's. But if you want a solid contributor every week from a yardage standpoint, you really can't go wrong with the Duce.
I have Curtis Martin and have been debating trading him for a couple of weeks now, but the dude is just lighting it up. He's at peak value right now, so if you're going to trade him, now is the time. In all honesty though, I think he's for real.
I don't think Chris Brown is for real. He's far too injury prone with his running style, so if you can get rid of him, I would do it. He's put up good enough numbers so far to get good trade value.
I value Corey Dillon quite a bit. As the weather worsens, the Pats will likely turn to Dillon more and utilize their ground game. His recent injury might spook some owners, but he should be solid down the stretch.
I'd try to trade away Michael Clayton if you can. Jurevicius and Galloway are coming back and should cut into the rookie's production.
