Not really seeing as Burke was brought in to clean up JFJ's mess and was pushed to win quickly because of those years. Nonis was meant to carry it on . JFJ made a lot of awful moves like trading Rask and the pick that landed Roman Josi with some real mediocre drafting set up the future GM's with a significantly tough task of rebuilding the team. Sure, Quinn didn't make it easy , but he inherited one of the better squads in the league and managed 1 playoff appearance in 4 seasons. At least with Burke and Nonis they managed to draft Kadri , Engvall , Johnsson , Brown , Rielly, Nylander and to a lesser extent, Verhaeghe.
I'm not sure how Fletcher set the franchise back, he traded away an injury prone defencemen and a struggling forward for a struggling forward. He shed salary by trading McCabe, Gill, and Kilger and brought in draft picks that didn't pan out, it happens. He did acquire Grabovski and draft Schenn, which isn't bad for a less than 1 year tenure.
