Actually, I would say do this deal, IF you aren't using Moreno as a starter. Blackmon will see the targets, and he's a great YAC guy. In PPR, he has a high floor, but probably won't be scoring too many touchdowns. Moreno has always been injury prone, and when the Broncos blow teams out, they tend to split the garbage time carries amongst the three backs. You probably can get a better WR for Moreno in a trade, but that of course depends on whether the other guy needs RB help.
thanks for your help on mine, i added an update: viewtopic.php?f=18&t=541403
