Waiver wire pick up?

Someone in my dynasty league just dropped Dion Lewis. I know he has been really hit or miss this season. I am currently #1, but not sure if he is worth using as my #1 waiver wire, I currently have Fornette/Yeldon, Mark Ingram ,Aaron Jones and the infamous Buck Allen (who I would probably drop),

I have had a rough year with Fornette being out and Ingram suspended. Now with Hyde to the Jags, I am sure that will have a negative impact on Yeldon.

Just looking for some thoughts. Thank you all in advance!

I’d drop Buck Allen for him in heartbeat in Dynasty. Shame to use the number 1 priority but really given the size of dynasty rosters and the lack of waiver wire guys, especially at RB he’s worth grabbing in my view. Hyde will probably be a FA next year again as will Ingram and Yeldon will be a handcuff so i would get another guy in that’s serviceable
