When the Flames first moved to Calgary in 1980, there were a lot of good players making the trip up north. One of the absolute best, though, was Kent Nilsson.
When Nilsson was traded, it was for a modest return of two second-round picks - one of which turned into Joe Nieuwendyk.
When Nieuwendyk was traded, it was for a prospect who had yet to truly break out (though that would come soon after): Jarome Iginla.
When Iginla was traded, it was for Matt Bartkowski, Alexander Khokhlachev, and a first Ben Hanowski, Kenny Agostino, and a first: otherwise known as who, who, and obviously.
