Nick Ritchie (@ $2.5 mil) was brought in to replace Zach Hyman (@ $2.25 mil) out at his old price point, and play in the top likely beside Matthews were he started the year.
However all 4 of those new additions at forward above (including Ritchie) for $6.2 mil Cap produce at the same rate as 1 X Zach Hyman .. 11 games 7 goals 3 assists 10 points for (@ $5.5 mil) new price point, at this point in time.
Leafs GM essentially believed in quantity of new additions to replace quality to address Leafs supporting cast and provide better secondary scoring around the core 4, however they're struggling just to replace Hyman. He could just re-signed Hyman and added Bunting @$ 950k for about the same cap as the new 4 combined and left unqualified RFAs Ritchie, Kampf and Kase for someone else .
Dubas was likely betting on Ritchie to meet and exceed his last year #'s of 56 games 15 goals 11 assists 26 points [= 82 games 22 goals 16 assists 38 points] when playing on a line with 2 of his core 4 forwards at any time to prop up his stats. Now he is already a 4th line hoping Spezza and Simmonds elevate him statistically.
You can't really compare 3 players to 1.
It's not Hyman ($5.5) vs Ritchie ($2.25) + Kase ($1.25) + Kampf ($1.5), totaling $5m, meaning you still have to find $500k. It's Hyman ($5.5m) + Brooks ($725k) + Ho Sang? ($750k) totaling $7m, meaning you still need to find another $2m.
The math also was not as simple as "we need to replace Zach Hyman" -- it was "we need to replace Zach Hyman, but we also have other needs on this team to address.
Notably, amongst their forward groups, they wanted / needed the following:
- "Replacements" for Zach Hyman, Nick Foligno, Alex Galchenyuk and Joe Thornton, with the latter being a fairly easy replacement.
- More toughness / size / ability to score in the dirty areas of the ice.
- The ability to create a pure shutdown line that does a ton of defensive zone heavy lifting.
The simplest way to look at it is probably that Hyman becomes Bunting, Foligno becomes Ritchie, Galchenyuk becomes Kase, and Thornton becomes Kerfoot, while Kerfoot becomes Kampf.
It wasn't so much a "replace quality with quantity" as it was, we've got 4 spots in our forward group to fill, 3 of which were pretty important players, and an area of need (a shutdown 3rd line C). He went with the approach of trying to address all 4 needs (knowing he doesn't have much deadline ammunition), rather than filling 1 need really well, but knowingly leaving gaps on the roster.
Maybe you can argue that "Joe" shouldn't have been replaced, and instead just rely on improvement from Mikheyev & Engvall, but then you don't sign Kampf, and you're stuck with Kerfoot in the #3C role.
Sure, maybe a bit of moneyball, trying to find diamonds in the rough, but it's not like the Leafs could go out and spend $3.5m to get a guaranteed perfect player. Boston signed Foligno for $3.8m. He's played 7 games and has 1 assist.
TLDR? If he signed Hyman, it's not at the cost of Ritchie, Kase, Kampf and maybe Mikheyev. It's at the cost of Kerfoot, Ritchie, and and probably Mikheyev, being replaced by Brooks and another guy making close to league min. That doesn't put the Leafs in a good situation, especially if Matthews or Tavares get hurt for any length of time.
