The Serby Mock 5.0 was an exercise in relentless hair-pulling and at times at the very end Olympic dart throwing as the most unpredictable, mystifying NFL draft — starting at the top, for crying out loud — mercifully arrives on Thursday night.

A pair of top-10 picks for both teams … unless Schoen trades down … unless Douglas surrenders his 10th pick in a Deebo Samuel tease.
