This is actually tougher than I thought. If you trade best/austin of johnson, that would leave you potentially thin at WR. I think Holmes may be fine, but there is risk there. Put it this way, which is a greater difference....Ausitn or Johnons and whatever WR you start, or CJ to Bradshaw or best. I think it's too big a hit at WR. I would stay put.
