Would you trade greg jennings for chad johnson in a fantasy league or is johson too risky?

I say Johnson is too risky. Plus T.J Houshmanzadeh is becoming Carson Palmers go-to-guy. Johnson has a serious injury that he is trying to talk down. but heis on a contract year which could be big but i think Aaron Rodgers will get the job done in Green Bay which could be HUGE for Jennings. Hands down keep Jennings.
