Fletcher is a good GM if your owner isn't asking for playoffs every year. Not that Leipold is wrong for doing so. But that doesn't mean Fletcher is a bad GM. Just bad fit.
If Fletcher went to an organization that didn't have an expectation tomorrow, I think you would see a much different and more patience Fletcher. One that was good at both hitting on 1st round draft picks and finding diamonds in the rough.
Leddy, Granlund, Brodin, Dumba, Tuch, Ericksson Ek, and Kunin is a pretty good record for drafting ~7-20ish.
Spurgeon, Dubnyk, Haula, Kaprizov, Seeler, etc. were also pretty good pickups for pennys.
