A lot of GMs lust for big RHDs, look at what Savard and Chariot got paid (both trades and extensions) and they're 2-3 years old.
It's a "hockey man" thang.
It's never been about "absolving Fletcher" but recognizing he's been scapegoated for the failures of the FO that go back a decade.
The problems go back to 2012, when Holmgren refused to recognize the obvious - with Pronger out, the rebuild should have started with the Richards/Carter trades. Pronger made that team a contender, without him they were no longer a top 8 team.
Fletcher has badly executed a bad strategy - which may end up a good thing - if he had, for example, made some better moves, the Flyers could have been a marginal playoff team for four to five years with little cap room as they sign G or JG, kept Ghost to let him walk after this season, kept Voracek only to see him on IR, etc. etc. Drafting 15-20th (and 45-50 in the 2nd rd) and ending up with a bunch of marginal prospects. Last decade repeated forever (hockey purgatory).
