DeSean Jackson or Nate Washington?

In fantasy football, which one should I start. A lot of people may think Im crazy, but Jackson is playing a tough Falcons D with Kolb playing QB. Kolb barely ever throws him the football. Washington is playing a soft Jaguars D and he is Vince Young's top TD target. Also, should I start Dwayne bowe against the Texans instead of these two
