Give up on Schaub or Vick for DeSean Jackson?

[StephanP89]

I have Schaub & Vick, been going back and forth in starting them and Vick has been killing Schaub's numbers. Schaub hasn't even put up more than 10 points other than in Week 2. I'm also worried that the Texan's running game is picking up over the passing game, so that doesn't help me much in QB fantasy points where as Vick is EVERYWHERE & is red hot. I have a guy who needs a new QB and has Farve. I could definitely get him to take Vick, but I might be able to get him to take Schaub instead....who should I give up? Schaub or gamble with Vick?
