The quote lacks context.
The Flyers (Dave Scott) were impatient, which led to the bungled mid-season firings.
I supported the patient roster approach because the primary holes in the roster are too hard to fill by making trades (goalie, 2 RDs; still don't see Ghost as a long term RD). 2C/3C, depending where they wanted NP, is a little easier to fill via trade and it sounds like Hexy tried to bring Stastny aboard as a FA. I was happy enough for the team to remain a competitive pretender while we waited for those holes to be filled from within.
However, I was adamantly opposed to keeping Hak around. He had plenty of opportunity to show his patterns and preferences and proved that he wasn't ready. The time to fire him was the 2018 offseason or during the 10 game losing streak. Not kicking the tires on Trotz was a mistake. Definitely became impatient waiting for the Hak firing.
Overall, I was happy enough with Hexy, but also supported his firing because he was watching a team play below the sum of its parts, mostly because he didn't address the unreliability of Neuvy (goaltending was holding this team back more than coaching), and obviously because he continued to support Hak.
Next year should be the year they were ready to contend, but now I'm not so sure. Unless Myers and Morin get good looks in the remainder of this season, there's likely to be two rookies on D next year, which usually doesn't bode well for a deep playoff run. In that, the Flyers may still be too patient, unless they can land a Karlsson type big fish in free agency.
