I don't have a ton of time, so I'm just going to respond to the post by overpass that was quoted in, specifically the following numbers:
There are some serious flaws with this analysis, unfortunately. Green only played 130 games over the prior two seasons (65 per), while Langway played all 160 games.
If we assume that Green had played the additional 30 games, it's (probably?) safe to assume the total GA of the Caps would have decreased. For the sake of comparison, I will adjust the numbers to reflect Green playing 20% more games (brings him to 156), and reducing the nogreen numbers by a corresponding amount (not correcting for 'quality' difference btwn Green and the #2 dman, though):
This change makes things look quite a bit different. Now we're looking at a 43 +/- swing, combined with a 32 GA reduction, and seeing additional GF for Langway. This raises another point: Langway, a primarily defensive dman, had a better ESGF than Rick Green, the Caps old #1 dman. This might indicate that Langway is receiving additional ES minutes, which could also help to account for the superior ESGA of NoLangway compared to NoGreen. Since we lack TOI numbers, there's not really a good way to check.
To sum: after merely adjusting for GP, we see that Langway's ESGA numbers resulted in a 32 GA improvement over two years compared to Green, and a 58 SHGA improvement compared to Green. Those are pretty substantial improvements over other #1 dmen. In spite of not having an offensive game, and being a defensive dman receiving the toughest assignments, Langway was a + player.
There is also the question of 'intangibles' -- why doesn't Langway, as the captain and best defensive player of the team receive any credit for the improving defensive play of his teammates, who are largely AHL quality dmen and rookies? Were they 'inspired' by his play?
Washington in 1980-81 and 1981-82

Rick Green | 146 | 172 | -26 | 0.85
NoGreen | 276 | 308 | -32 | 0.90
Washington in 1982-83 and 1983-84
