Don't know about in hockey but in the 80s Bill James did a study of "record in 1 run games". You'd hear a lot by commentators "Boy this team is good, they just have a knack for winning those 1 run game." But James found that generally, GOOD teams win by multiple runs, and when they lose, they lose by 1 run frequently. Conversely, when bad teams win, they generally only do it by a run, while they lose big frequently.....
So... record in 1 run games wasn't a good indicator of a team's actual success overall.
Apply that to this question anyway you want.
