Are there any decent WRs on waivers? As FiveThous noted, your WR depth isn't great right now and won't be until Gordon comes back. Royal is a decent enough flex play, but obviously I don't expect him to score twice every week like he has the last two. Patterson has upside, but right now he's just not getting the targets to be a reliable starter in a PPR league, and the Vikings have pretty much failed to utilize his unique skill set much at all the past two weeks.
I agree that MJD should probably be dropped. There almost has to be someone better on waivers.
