After playing 10 seasons combined with the St. Louis Blues and Calgary Flames, Joe Mullen would bring to Pittsburgh a resume as a previous Stanley Cup ring (Calgary in 1989) and was a two-time Lady Byng Trophy winner.  You could argue that Mullen was stolen, as Calgary gave up a 1990 second round pick for him, as they thought he no longer would be productive as he dropped from 110 to 69 Points.  They would be wrong.

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, but he was on a line the season after with Mario Lemieux, and he took advantage of the golden opportunity.

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