Actually, I'd take the second trade. I'm not overly impressed with your WR corp. Boldin and Manningham are doing nothing. And the Raiders have no clue how to use Moore, and with DHB having 2 big games, he may be used less. I'd take Colston. Looking at you WRs, it seems like Colston would start on your team basically every week. So you'd be giving up your 4th best RB (who may rarely make your starting lineup) for a WR who would probably constantly start. That's a good deal in my book. I know that its hard to fully trust a NO WR, but I'd take Colston in my lineup over Boldin, Manningham, and Moore anyday.
EDIT: I don't know how big your league is, but if you play in a 10 team or less, the first trade may not be a bad idea either. Again, you'd be giving up 2 guys who probably wouldn't crack your starting lineup (i really don't like Boldin or Greene...especially Boldin) so this trade wouldn't be so bad. Especially if your not in a deep league cause you can play the wire.
