Pick 3 RB's please

[cfiems]

Steven Jackson vs. MIN
Slaton vs. ARI
Portis vs. Carolina
Mendenhall vs. DET
Coffee vs. ATL
Harrison vs. BUF

Right now I have Mendenhall and Coffee. I need a third. Slaton finally broke out last week. Portis is running against a weak run defense. Harrison had a good week last week and has a favorable match up. Jackson is on a bad offense and has a terrible matchup.
