Dynasty Impact: The Raiders get one of the top players in the draft at five and, in the process, get a pass rusher they haven’t seen in a while. He played weak competition but has an undeniable nose for the ball and should be a force in the AFC West for years. For dynasty purposes, Mack could rack up a ton of sacks using his speed and explosion. Mack should be one of the first linebackers taken off of dynasty boards.
