Denarius Moore. As with any NO receiver, the targets are highly variable since Brees like to spread it around. Moore is THE guy in the Oakland passing game, and Palmer will be looking for him frequently. Moore might have a higher ceiling, but he also has a lower floor. I'd take D Moore.
I'm confused. Do you play 4 WR? Looks like you've got 3 guys starting right now, and I like McGahee over either Moore as your flex. In any event, I like Lance more than Denarius for the reason the poster above me mentioned: he's in a better offense.
