So in your mind no GM can do better with the same "circumstances" surrounding Chuck.
Cant draft better, make better trades, make better assessments, , make better hires. Is this what you really believe?
Would you take this job if you had alternatives with the current FO? Knowing the advisors call the tune?
That you won't be allowed to take a step backwards to fix the roster?
Knowing you're expected to make the playoffs instead of build a team?
Fletcher could have done better, but unless you think another GM was going to pull off miracles, those moves wouldn't have made much difference. So you keep Ghost instead of Risto, you have a 1st and a couple 2nds, but you're still expected to add veteran players up to the cap to try and make the playoffs.
Flyers didn't have tradeable assets to make moves unless you move players like TK or Provorov, and then you have to replace them, so you're just running in place. Ghost had negative value, Voracek had negative value, JVR had negative value due to their contracts.
Fans talk about trading players for picks - uh, that's called a rebuild - and that was what got Hextall fired (along with his personality and failure to find a better goalie). The FO wouldn't have allowed any GM to do that, Holmgren made that clear when Fletcher was hired.
