0.5 points per first down wr value

I’m in a league that gives 0.5 points for first downs and I was thinking of picking up Amendola off the waivers. Does the extra for first downs make players like Amendola or Beasley more valuable as they are the veterans who are more likely to be targeted for making safe first downs? Or should I just see it as a nice bonus and value players pretty much the same. Was going to let go of TreQuan Smith or Albert Wilson to pick Amendola up. Thanks
