Hmm, Portis and Slaton are pretty much a wash in my book... I do give the slight edge to Slaton, either though should be solid. Sorry its not a definitive answer but I don't think you can miss either way, go with your gut.
Slaton is definitely the better RB for PPR leagues. If not, Slaton is still probably the better pick because Portis has alot of mileage on those legs and is not getting any younger.
Yeah, I like Slaton more, he is on a better Offense and could break-out again. I just can't stand those outfits of Portis'. Help me: viewtopic.php?t=442511
QB: Brees, Rodgers, E. Manning RB: D. Mcf, Grant, L. Wash, R. Rice, D. Brown WR: Megatron, Driver, Hester, Ginn, N. Washington TE: Shiancoe, Fasano K: Elam D: Packers 12 teams, PPR league
Both are good players, I could not find how many players you could keep. I think Slaton has move value in a PPR, keeper league than portis. He is too inj prone.
