It all boils down to wether or not you think you will make the playoffs. Because I can tell you that Fred has a TERRIBLE schedule coming up. When is your trade deadline? I'm guessing soon? As you obviously know, Austin's value couldn't be any lower than what it is. If you can afford to wait a week or so for him to have a big game (or even a TD...) you might be able to get more value.
That being said, I know how hard it is to make trades in fantasy and if you are stuck between a rock and a hard place I don't think its going to have a huge impact on your team.
One thing to consider, if you DO get to the playoffs, Austin has some nice wk 15/16 matchups, and reports are Romo could be back then, thus making him a WR1 again... Hope this helps.viewtopic.php?f=18&t=486297
