Maybe, but lower in the draft Metcalf's physical ability and potential at his position is more elite than any of those players. And looking at Beane's first draft, in the first round he bet on players who were raw, but athletic, physical freaks of nature with potential to dominate at their positions.
Ed Oliver fits that profile too, although he is not raw and has a history of production which is why I believe Beane would grab Oliver at 9, but not Metcalf. But lower in round 1? Hard to pass on Metcalf's potential.
