Week 10 of the NFL season is when most leagues set up their trade deadline. With that in mind, I recommend taking a look at Kyle Wood's Trade Targets article as he highlights some players you might want to consider trading for and trading away.
I want to talk about trading etiquette. Generally speaking, you've got to be very proactive as a trader. Communication is key. This means sending good offers. What is a good offer? If you need a RB and the other team doesn't have much RB depth, it's best to not send a trade offer without asking that manager if a certain RB is available.
