We start 3 RB and 3 WR. My roster:
RB: WParker, THenry, RudiJ, LJordan, AGreen, SMorris
WR: Boldin, Bowe, SMoss, VJackson, Marshall, Berrian

Should I try to trade Jordan for Holt? (he needs RBs badly)

I'd try to move Rudi first, but that might be a hard sell. The problem is that you may also lose Henry to suspension in the near future. I'd absolutely keep Parker and Jordan at this point. Maybe you offer Rudi or Henry and a back-up WR, such as Marshall or Berrian.

And yes, I think Holt's numbers will improve as well as Bulger's. If you make the right offer, I think you can upgrade nicely.

thanks Bullies...If I trade Jordan I would hope to fill the vacant roster spot with Selvin Young, who is a free agent.

The only problem with that is you're speculating Henry will be suspended, and that Young will step in and perform at a relatively high level. There's still some uncertainty there.
