Bob McCammon and Pat Quinn (Larry Hillman, ex-Flyers' player, coach of Winnipeg in WHA) were the finalists for the Flyers' head coaching job after Fred Shero took the Rangers' post. McCammon got the Flyers' job and Quinn (Flyers' one-year assistant at the time) was sent down to the AHL to get more seasoning behind the bench. After a few months into that season, McCammon, still green at the NHL level and with a team not firing on all cylinders, was demoted to the AHL while Quinn was promoted.
McCammon was a favorite of Ed Snider. He had the hockey acumen -- many of the Mike Keenan players were on the team due to McCammon's management team -- however, he never seemed to develop ideal relationships with many players. Quinn, just the opposite, was a player's coach, guys would go thrugh brick walls for him. The Flyers eventually got rid of Quinn with eight games remaining in the 1981-82 regular season because the team struggled especially against the Rangers, who were the eventual first round opponent. McCammon the manager was much better then McCammon the coach, is a recurring theme.
Quinn had a patchwork defense. The injuries were something phenomenal. He didn't exactly have too many all-stars back there either. That is what cost him his gig, unfairly. The backline was eventually redone with the likes of Mark Howe, Brad McCrimmon, Doug Crossman and Brad Marsh all through trades.
