That is at least incomplete. Rutherford himself made the team that played with speed. From getting Kessel, hiring Sullivan and signing players who could make this our MO (again) - Daley and Hags being transformative, while bringing up quick kids from WBS.
You can say that he went away from that, but I don't think it was a conscious decision as much as it was subsequent signings being bad/not working out anywhere near like the former ones did, while some of our guys took a clear step back at the same time (Rust, Horny, Maatta and Geno this season).
Matt Hunwick last season was an attempt at getting a player whose strengths - or perceived such - better fit the speed game than Ron Hainsey (who I wanted to keep if salary permitted, and who was btw. the Leafs best D-man against Boston). Jack Johnson they seem to have just completely misread, or perhaps Sid had too much of a hand in that... something rarely speculated on.
Rutherford on getting Johnson: “One of the things we lacked last year was three pairings that we had a puck-mover on. Jack’s a good skater, good puck mover. He can play both sides. He can play on either special team.”
I think he said basically the same about Hunwick, which didn't seem completely inane after the playoffs Hunwick had. I mean, it has turned out to be comically wrong (in both cases), but the player evaluation more so than then reasoning leading to wanting such a type of player. They wanted 2016 Daley, they got JMFJ.
That's still on JR, but it doesn't mean its the vision that is wrong or lacking.
I also think we have had occasions where there was young speed to utilize, but Sullivan simply chose not to, going with physical instead. Moreover, that there is a total disconnect between the D and F, that players look devoid of options and we were both an abomination in giving up odd man rushes and allowing short handed goals against this season - that goes to coaching (or the coach not getting through) much more so than it does the GM.
