It is not possible to know how good DK Metcalf will be. Today, I don’t really care. Seattle drafted Metcalf on my birthday, and I look at the young wide receiver as a gift. Sometime very soon, that gift will be unwrapped, and for all I know, it might be an avocado. But while we can still crease the wrapping paper with nervous anticipation, let us dream about just how good Metcalf might be.
To do this, I am going to extrapolate from Brad Oremland’s work at Football Perspective. Specifically, I wanted to know what happens when a team adds a player who will come to be known as either the fastest receiver or the best deep threat of their era.
