Rob Brown began his NHL career with Pittsburgh when the 4^th Rounder debuted for the big club the year after.  Brown had a good rookie year, scoring 44 points.  The following season, he was on a line with Mario Lemieux and took advantage of the golden opportunity.

The Los Angeles Kings claimed Lowell MacDonald in the Intra-League Draft, and realistically, there was no reason to believe that when the Penguins chose him, he would become a productive NHL player.  That being said, his was the strange expansion world of the 1970s, and that is precisely what he would become.  

Although he was a proven scorer with the Maple Leafs, he was not a fan-favorite in Toronto. As the Leafs were looking to rebuild anyway, Kessel was shopped around in the summer of 2015.  They found a taker in Pittsburgh, and it turned out to be one of the smartest transactions that the Penguins ever made.
