What if Connor Hellebuyck really is the fix for the Devils' goaltending?

The Devils are 7-4-0 and sit among the East's playoff teams, yet their goaltending ranks 24th in the league in team save percentage. Connor Hellebuyck makes his first start for them in Dallas tonight, so the useful question is not whether the trade was fair. It is what happens to this season if he stops pucks the way he usually does.

This is a hypothetical, built on real numbers and one stated assumption.

The size of the edge

Hellebuyck stopped .925 of the shots he faced in 2024-25. Last season, in a rougher year for Winnipeg, he finished at .895 over 57 games. Even the weaker of those two seasons is a goalie who holds up in volume. The gap between his two seasons is .030, which is the swing the Devils are betting on as much as any comparison with Jacob Daws-era numbers.

Turn that gap into goals. Over 1,000 shots, a .925 goalie lets in 30 fewer goals than a .895 goalie. That is the whole mechanism. No scheme change, no new defence pairing, just 30 pucks per 1,000 that stay out of the net. A team ranked 24th in team save percentage is giving some of those goals away every night, and a goalie at his best level takes them back.

What it means in the standings

The Devils spent a lot to land him. Winnipeg received forwards Dawson Mercer and Nick Bjugstad, goalie Nico Daws, a prospect and picks, and New Jersey took on his full $8.5M cap hit with no salary retained. His contract runs through 2030-31, so this is a long bet, not a rental. Goals saved convert to points in the standings, and in a conference where the last playoff spots are often decided by a handful of points, a goalie who erases a few extra goals a month matters more than another depth forward.

The market already moved. Kalshi, a prediction market and not a statistical model, had the Devils at 55% to make the playoffs before the trade and 70% afterward, according to the New York Post. Lindy's Five is lower at 60%. The spread between those two numbers is the real debate: one believes the goalie fixes the problem, the other wants to see it.

The case against the best version

The 2025-26 season is the warning. A .895 save percentage is not a disaster, but it is far from the .925 that built his reputation. If the Devils get that version, the improvement over their current group shrinks, and the extra cost in cap space and roster depth starts to show. Public goals-saved-above-expected figures for his last season also disagree widely from site to site, which is a reason to be careful about promising a return to form.

The best-case version is simple. Hellebuyck plays close to his 2024-25 level, the Devils keep scoring, and a team already in a playoff position gets safer every week. The middling version still helps. The version that hurts is the one where the .895 season was the new normal. Tonight against Dallas gives the first look, and one start settles nothing, but it is the first real data point in a season that now rests on his crease.
