Some roster help?

So I drafted with a 10 man full PPR team this year and I drafted with a different strategy. I went WR heavy. So two questions. What are your opinions on my roster? And mike Williams is free right now along with Antonio Calloway…if I were to pick up one or both of them, would anyone on my bench be worthy of dropping? Thanks so much for the help! image image

I would drop the Def or Kicker for Williams.
