Maybe some of these win-streaks had players who missed the only loss before/after the streak, and hence their win streaks continued?
All Time Longest NHL Winning Streaks
Though maybe some of those players also missed some of the wins, which then would be deducted from their streaks. And of course if they missed more than half of game due to injury or sickness, like Patrik Laine in his current win-streak.
Can someone check with SDQL? Maybe we can even define a concrete "win-factor" or similar, i.e. if a specific player is an actual huge win-factor as per this stat.
