Teams With the Most Momentum Heading Into the Playoff

Statistical momentum in the Stanley Cup Playoffs is often all over the place, but the second round of the 2026 postseason isolated a few franchises that actually got their tactical stuff right, at the right moment. As the league eases toward the Conference Finals, the numbers look pretty clear: the Carolina Hurricanes and Colorado Avalanche have the most durable statistical “shape”, while the Atlantic Division bracket brings this more chaotic, high scoring kind of swing.

Carolina’s Methodical Perfection in the East

The Carolina Hurricanes show up for the Eastern Conference Final as the go to version of postseason momentum, after finishing an 8–0 run, sweeping both the Ottawa Senators and the Philadelphia Flyers. Their game management feels grounded in special teams detail and structural steadiness, not in those random, volatile offensive surges.

Over the second round, Carolina kept the Flyers pinned, limiting them to a 5.2% power play conversion rate. They essentially shut down 18 of 19 man-advantage sequences, which is… pretty brutal. On offense, Carolina’s five-on-five has produced a 54.3% Expected Goals Percentage (xGF%), meaning they’re usually controlling the puck and landing higher quality attempts. Behind that, Frederik Andersen’s .934 save percentage adds a ton of reassurance. Carolina can soak up pressure then punish transition mistakes, so they end up with this elite statistical floor that makes them the real heavyweight in the East.

Colorado Reclaims Control via Five-on-Five Efficiency

In the West, the Colorado Avalanche absorbed a mid-series push from the Minnesota Wild, then still walked out with a 4–1 series result, keeping their claim as one of the toughest crews in the bracket. Minnesota did get a quick jolt during the middle portion, with that 5–1 win in Game 3 that basically interrupted Colorado’s flow. But Colorado responded by adjusting their neutral-zone tracking, and then closed things out with back to back wins, including that 4–3 overtime finish in Game 5.

Colorado’s momentum base mostly comes from their high-danger chance conversion. Across the second round- the Avalanche averaged 4.8 goals per game, fueled by top-six forward sharpness and that constant blue-line pressure from Cale Makar. Even more, they cleaned up discipline problems from earlier in the month. After conceding five power plays in their only loss, they held Minnesota to fewer than three man-advantage chances per game for the rest of the set. Those structural fixes should help Colorado enter the Western Conference Final versus the Vegas Golden Knights with healthier balance across key metrics.

The Volatility of the Atlantic Division Bracket

Meanwhile, the matchup between the Buffalo Sabres and the Montreal Canadiens reads like the opposite storyline, more or less, predictable momentum wise. They were locked at 3–3 as they moved into the winner-take-all Game 7 on Monday night, May 18. Both clubs have traded these loud, blowout type outcomes, including Buffalo’s 8–3 surge in Game 6 to avoid elimination.

Buffalo does have the visible scoring carry, especially after netting seven unanswered goals against Jakub Dobeš. Still, the deeper indicators point to some fragility. In postseason play, the Sabres are allowing about 3.0 goals per game, and at five-on-five their expected goals against (xGA) stays elevated. Whoever wins this series is likely to pay for it physically, and also start with immediate structural drawbacks, because a rested Carolina group hasn’t needed to play since wrapping up its sweep on May 10. So for either Montreal or Buffalo, surviving this round effectively means they have to lock down defense right away otherwise Carolina’s rest advantage turns into a real problem fast.
