It’s 1980. The second NHL Entry Draft is about to be held where its predecessor Amateur Draft was always held, in Montreal. The Canadiens had the first overall pick obtained from the Colorado Rockies for Ron Andruff and Sean Shanahan. It’s not the first time the Canadiens traded to get the first overall, but it would be, until present time, the most recent.
Although the Amateur Draft became the Entry Draft in 1979 (done to include junior-aged players who had begun playing professionally for the defunct World Hockey Association), the 1980 Entry Draft was really the inception of the modern-day draft as we know it.
