This draft is not weak at X WR dude. Literally the best WR in the draft is a Big C receiver, then you have Tre Harris, Ayomanmar, Bech, Higgins, not counting all the TE’s
Ayomanor and Bech might be able to be Big X, but they might be slot guys or just all around WRs. I saw there is questions about Ayomanor's knee holding up, so he might drop because of that, who knows.
Harris could start out as a Big Z and develop into a Big X.
Point being, there is not a lot of Big X guaranteed WRs in the draft whereas you know exactly what you are getting in DK.
