Who to pick up Burleson or Berrian?

I would pick up Burleson. I don't care if Helbeck is out. Burleson has been targeted more than 12 times these last two games. That is 5th in the league in the first 2 weeks. Wallace is going to have a good game, although he is no Helbeck. Berrian? I don't know much about picking him up. Adrian Peterson and the Vikings run the ball and Percy Harvin is stepping in and going to be a force to be reckened with.
