Is this an even trade?

When playing fantasy football, esp. this year, I have learned RB's are hard to come by with all the injuries and such. This is obviously part of the trade, one giving up a RB and one getting a RB out of it while giving up a WR and TE as well. I would say at this point in the season, do what is going to protect your team and get you into the playoffs. Don't give someone else in your league the advantage over you. Witten and houshmandzadeh are huge for one team to have. I would say Team A should try and pick up Ryan Grant of GB, he will be starting now and is a good pick up. It isn't a bad trade but just think about all options first and project how this will help you down the road. Look at each players sched, for the remainder of the season. That is the advice I would give.
