It’s tempting to call the Henri Jokiharju trade the cherry on top of a delicious offseason sundae for the Buffalo Sabres, but GM Jason Botterill can’t quite desert his office just yet, as his work might not be done yet.

Here’s a delicious thought, though: the Sabres would be massively improved even if Botterill did decide to close up shop and spend the rest of the summer reclining and sipping cocktails.

Loading up on the right

Really, you can go back to the 2018-19 season to see the Sabres getting proactive about improving their defense, the team’s most glaring weakness. Botterill really started the party by snagging Brandon Montour from the Anaheim Ducks in February, and continued his trend of trading for interesting right-handed defensemen talent by getting a bargain for Colin Miller, then making what looks like a lucrative trade in receiving Jokiharju for struggling prospect Alex Nylander.

Jokiharju, Miller, and Montour could set up a glut on the right, as they’re joined by beat-up blueliner Zach Bogosian, Casey Nelson, and hypothetical trade generator Rasmus Ristolainen. You can basically set your watch to Ristolainen rumors cropping up, either when Buffalo adds a right-handed defenseman, or even if they just add money. Or maybe get out of bed in the morning.

The logic is simple enough. Ristolainen is, in many ways, a lot like former Sabres defenseman Tyler Myers. Ristolainen and Myers are both very tall, and they both signed contracts after a spike in production, only to slide rather than continuing to climb afterward (in Myers’ case, the shaky contract he signed way back when with the Sabres just expired).

Ristolainen is 24, and his size and respectable skill could make him intriguing to front offices that … well, frankly, don’t really look very deeply into a wide variety of numbers. If it weren’t for lousy plus/minus stats, Ristolainen would check every “traditional” box (four consecutive seasons of 40+ points, big ice time averages), while looking far worse in fancier ones. Take these RAPM charts from Evolving Hockey, which paint the picture that Ristolainen doesn’t bring a lot of value beyond the power play, and you’ll maybe begin to understand why analytics-minded Sabres fans are anxious for Buffalo to trade Ristolainen while there are at least some NHL front offices who still believe in him:

Again, a significant subset of people – analytics folks, plenty of Sabres fans, and those who meet in the middle of that Venn Diagram – have been clamoring for the Sabres to trade Ristolainen for some time, but this summer’s set of moves makes such arguments more credible than ever.

That’s because …

More help for Eichel, possibly with more help on its way?

One more top-six forward, by way of a Ristolainen trade, could really tie this roster together.

To Botterill’s credit, he’s deftly improved another problem area beyond that once-abysmal defense, as he’s given the Sabres more scoring options beyond “Hopefully Jack Eichel saves us.”

The most important first step was keeping the one true running mate that Eichel had, as they signed Jeff Skinner to a monster contract. While you could argue quite fairly that it’s an overpay overall, I’d also rank it as a necessary evil.

But, again, the Sabres’ 2018-19 season showed that they need more than Eichel – Skinner, as powerful as that duo turned out to be. And now Botterill faced the challenge of adding support without breaking the bank, as Eichel + Skinner = $19M in combined AAV.

You know what? Botterill’s done really well in that regard, too.

Jimmy Vesey isn’t a world-beater, but the Sabres courted him for a while, and now they have him for cheap. Vesey and 2018 summer acquisition Conor Sheary rank as the sort of forwards who won’t revolutionize your lineup, but could nudge you toward competence. It doesn’t hurt that both Sheary and Vesey will have the added motivation of contract years, either.

Marcus Johansson might be my favorite recent forward addition, if not favorite single add overall. The Sabres sat out the most frenzied part of free agency, and were rewarded for showing even just a modicum of patience. A few days after July 1, Buffalo added Johansson for an AAV of just $4.5M, and mitigated most of the health-related risks by only giving him two years of term. Splendid stuff, especially since the winger gets a chance to sign a more robust deal if he can deliver during the next two seasons.

That’s all good stuff; now imagine if Buffalo gets greedy.

Again, people get excited about the idea of Ristolainen being traded, as he’s prominent enough to be part of a blockbuster, as his $5.4M cap hit is both movable and large enough to be part of a hefty deal.

Sabres fans should salivate at some of the names thrown out there, as they could provide that one extra piece that truly rounds out a top-heavy offense into being nicely balanced.

Die By the Blade trots out two interesting scenarios with the Winnipeg Jets: perhaps the Jets would cough up transition machine Nikolaj Ehlers for Ristolainen. If not, what about the intriguing combination of young Jack Roslovic and analytics darling Mathieu Perreault? The Jets have been willing to shrug their shoulders at analytics before (see: Myers, Tyler), so after losing Myers and Jacob Trouba, maybe they’d want Ristolainen?

Ehlers, in particular, excites as a buy-low trade, but he’s not the only option.

Honestly, I was half-joking here, yet if the Oilers would bite on Ristolainen for Ryan Nugent-Hopkins trade, poor Edmonton fans might get another taste of Peter Chiarelli-style blunders even after Chiarelli’s been replaced by Ken Holland.

Basically: the Sabres could move from what’s suddenly a position of strength to pull the trigger on a Ristolainen deal, and maybe get a top-six forward who simply brings more to the table, at a comparable cap hit. If it’s Ehlers, that player could pan out and bring a lot more to the table than Ristolainen, who profiles as a deeply flawed player.

To be continued?

All of that said, if the right deal doesn’t sprout up for Ristolainen, the Sabres may also look at next summer as the true feeding frenzy.

The Athletic’s John Vogl paints quite the picture (sub required) of the Sabres courting potential free agents if they let certain expiring contracts fade, rather than re-signing people:

They can take Taylor Hall and Nicklas Backstrom to dinner on Delaware Avenue. Jason Botterill can sip mai tais on a Canalside tiki boat with Alex Galchenyuk, Tyler Toffoli, Torey Krug and Roman Josi. If the Sabres are feeling really frisky, they can wine and dine Matt Murray and Andrei Vasilevskiy.

Interesting stuff, and for all we know, Braden Holtby could also hit the market if the Capitals decide to roll that way with another cap crunch impending.

***

Even if the Sabres flip Ristolainen for that elusive top-six forward, they’d still need some things to break their way for this to feel like an immediate success.

Ralph Krueger needs to show that he won’t struggle coaching in the NHL after taking a truly unusual path back to the league, which included a lengthy detour with the Premier League. Botterill didn’t plunge into the goalie market, so they’ll hope for good work from Carter Hutton and RFA Linus Ullmark. It’s conceivable that they still might ask too much of Eichel, particularly if they can’t use Ristolainen for an upgrade. The Atlantic Division also looks formidable, with the Panthers at least spending like winners, along with the Lightning, Maple Leafs, and Bruins seemingly slated to make everyone else fight for wild-card scraps.

Overall, though, the Sabres improved immensely — and after the undeniable (but maybe unavoidable?) gamble on Jeff Skinner, they didn’t ruin their outlook in the longer term for the sake of short-term gains. By most accounts, they had a strong 2019 NHL Draft haul, to boot. Other teams looking to take those agonizing next steps from a rebuild to actual contention should take notes of what Buffalo did, and may still do.
