Ottawa's Rebuild Has a Cornerstone. The Problem Is Nobody Knows If He's Coming Back Healthy.

Every franchise reset has a load-bearing wall. Tear down the captain, bring in unproven pieces, sign a veteran on a short deal to paper over the cracks — all of that is manageable if the foundation holds. For the Ottawa Senators, that foundation has a name: Jake Sanderson. And right now, nobody in Ottawa can tell you when he'll be back on the ice.

Here is what we know about last season's version of Sanderson: 37 points, a plus-7 rating, and nearly 24.5 minutes of ice time every night. In a lineup that won only 43 percent of its one-goal games — a collapse that cost Ottawa roughly 11 points and ultimately the playoff spot they spent a final-month surge trying to claw back — Sanderson was one of the few players who consistently made the team harder to play against. He was the best defenseman on a roster that needed elite defense desperately. Now he's sidelined with an injury that, as of mid-July, carries no clear timeline. That opacity is its own kind of alarm.

The historical precedent here is not kind. Look at the franchises that tried to rebuild around an injured cornerstone defender — teams that moved a franchise player, signed complementary pieces, and then watched the whole architecture wobble because the one indispensable piece couldn't play. The 2010s-era Avalanche chased that problem for years after losing their defensive anchor to injury during a rebuild cycle. The lesson is always the same: you can add perimeter talent, but you cannot replace a top-pairing defenseman who logs 24-plus minutes a night with roster depth. That player is irreplaceable in the short term, and his absence cascades.

Ottawa has compounded the risk in ways that deserve scrutiny. Trading Brady Tkachuk — whatever you think of the long-term logic — stripped the team of its most physically imposing forward and left the left wing position bare. Acquiring William Eklund from San Jose is a bet on upside, not a guarantee of production. Signing Jordan Spence to anchor the blue line alongside Sanderson only works if Sanderson is actually there to anchor alongside. Artem Zub is also out. Ridly Greig is suspended. The depth problems are not theoretical; they are stacking up in real time. My read is that this front office made a series of moves that only make sense if Sanderson returns at full capacity — and right now, they cannot confirm that he will.

The offensive dependency problem doesn't help the math. Tim Stutzle put up 50 points in 50 games last season, a point-per-game pace that carried an offense that had no business being as functional as it was. Claude Giroux, back on a one-year deal to begin his 20th NHL season, posted 32 points and led the team in plus-minus at plus-13 — a remarkable number for a player his age, and a genuine credit to his professionalism. But Giroux is a one-year bridge, not a foundation. When the offense runs through a single center and the defense runs through a single defenseman, you are one injury away from structural failure. Ottawa is already living that scenario on the blue line.

I will make the declaration plainly: if Jake Sanderson misses significant time in 2026-27, the Senators will not be a playoff team. Not because the other pieces are bad, but because the margin for error in a 44-38 team that already lost close games at a historically poor rate is essentially zero. The one-goal game problem was not a fluke — it was a pattern that held across an entire season, and it requires a defense that can protect leads in the third period. Sanderson is that defense. Without him, Ottawa is running a rebuild on a cracked foundation, hoping the new paint holds.

The Senators made bold moves this summer. The Tkachuk trade will be debated for years. But the most important transaction of Ottawa's offseason isn't happening in a front office — it's happening in a training room. Everything hinges on one defenseman getting healthy. The clock is running, and the Senators still don't know what the answer is.
