Mike Williams was dropped in my league

Somebody dropped Mike Williams in my 16 team PPR league (dumb, I know). This is a big league, and waiver guys are tough to come by. How much FAAB (out of 100) should I spend to pick him up? My other receivers are Odell, Cooks, Sutton, and McLauren (Just acquired). I will be ok until Williams comes back from injury… if he sits out at all. To pick him up, I will be dropping a RB of little to no value, so that is not an issue.

I am thinking I should go pretty hard with my FAAB to acquire Williams. What do you think?

50, maybe 60
