Quinn finished the year putting up 11-points in 14-games then added 11 more in 13 playoff games for the Blues but it wasn't enough to secure him a spot in the lineup.
In an effort to fix this Quinn was packaged up with young forward Rod Brind'Amour and dealt to the Philadelphia Flyers in exchange for tough defenseman Murray Baron and centre Ron Sutter.
While Brind'Amour was an immediate success in Philadelphia, leading the team in scoring, Quinn struggled to find the net and managed just 37 points in 67 games.
Quinn failed to find a new club over the summer before finally signing a deal on the eve of the 1992-93 season with the Minnesota North Stars.
Quinn got off to a slow start with the North Stars with no-goals and just four assists in his first eleven games before his season - and his career - got derailed.
The Senators usual first line centre Alexei Yashin was holding out for a new contract pushing Quinn into a primary role where he delivered for the club.
Quinn's production dipped in Philadelphia with 22 points in 35 games despite the fact he was slotted in, briefly, on the Flyers top line with John LeClair and Eric Lindros.
Quinn signed a one-year deal to return to the scene of his high scoring seasons in Pittsburgh but he was unable to replicate his success.
