Which Rookie WR, Crabtree or Harvin WHIR

[Netsfan5]

1 pt per 10 yards rushing and passing
6 pts per TD
NO PPR

I need help on my final spot, Harvin or Crabtree. I think Harvin can be more explosive, but if the migraines suddenly show up then I'm screwed. Crabtree has been solid but not as explosive except for the TD last game.
