Draft Network has him currently as their 15th ranked receiver. (actually have Duvernay slotted 13th currently despite some of their scouts being lower on him)
WalterFootball has him as their 16th ranked receiver, projected anywhere round 2 - 4.
I think you also factor just how absolutely loaded this WR class is, in another year Duvernay's college production could have him starting off as a 3rd - 4th rounder baseline but this year he gets pushed down because of the sheer amount of quality prospects at the position.
