Waiver Wire stashes for weeks 15/16 help!

Ok so luckily I was able to lock up a first round bye so I’m trying to pick up players this week in preparation for the final two weeks. Need some help on who you would drop and pick up!

On my roster:
WR: Evans, Thielen, Ridley, Crowder, Hilton

On Waivers:
WR: Washington, Miller, Pascal, Shepard, Josh Gordon, Cobb, Anderson

I’m thinking of dropping either Crowder or Hilton for Shepard because Ridley’s week 15 is against the niners and I need to slot someone in at Flex that week.

Thanks for the all the help Footclan!
