Love is a duel
What a silly argument. First, seventies didn't claim that the point is "obvious"; Killion did (though not in so many words). Second, no one claimed that the four-color theory was intuitively obvious. The difficulty in mathematical proof in this case does not somehow exalt our "common sense", because there was never a claim from common sense made in regard to this problem. Yeah, it's a difficult mathematical proof. So what?
If this claim is like the four-color problem and cannot be resolved without going to great lengths, then that precludes our conclusions in this case coming from any kind of direct experience. This is nothing but classic scorched-earth anti-rationalism. But if our common sense here isn't a distillation of experience (unless you think our brains are secretly supercomputers), then we are left with nothing but the crudest form of synthetic a priori "knowledge": the claim is true because it makes sense to us intuitively.

Chris Pronger / Michael Leighton
2010 Stanley Cup playoffs - big physical Chris Pronger allows the Flyers to go to the SC finals with a very weak goalie - Michael Leighton. Pronger's size and physical style anchored similar play by the Flyers defense, compensating for Leighton's lack of talent.
Without Pronger - concussed, Leighton quickly disappeared from the NHL scene.

Zdeno Chara / Tim Thomas
Consider the NHL performance of Tim Thomas before the 2006-2007 season and since when protected by Zdeno Chara. Very striking difference whether viewed traditionally or numerically.

Chara is also a very good defenseman too, is he not?
and regardless, it's not like Thomas is the poster child for "70 game workhorse goalie".

Yeah, would be nice to see an example or two of this happening with big Dmen that were not considered elite/Norris caliber. I don't think anyone is going to argue against the statement that playing behind an elite/Norris caliber Dmen allows a goaltender to play more games
What about elite D who aren't big/physical?
Lidstrom.
Problem is I think you can find exceptions to any statement. Was it really defensemen getting bigger, as all players were getting bigger, while the game was evolving on several levels (inclusive of goaltender style of play, equipment, and training level). My point that simply observing something doesn't mean a cause and its effect has been found. The traditionalists are bogged down with claims of causation, while the other side insists that any claim of effect must have a correlation.
Consider also that introducing coaching systems whose aim was to shut down offense (Dead Puck Era and neutral zone traps) probably had something to do with the amount of time a goalie could play. In recent times, I remember Dom Hasek roaming all over the Wings end of the ice to keep from falling asleep. They were so good at puck possession and keeping the play in the opposite side end, their goalies didn't have to work very hard at all.

No, I'm not even sure of that, to be honest. I think it would make their stats better, but does that lead to more games at all? And if so, is it because they're less fatigued, or is it because they're perceived to be performing better thanks to better stats as a result of an elite defenseman?

Likely it would be a combination of both...I was thinking about the perception part myself.

Three Dimensional Aspects
Hockey is played in three dimensional space. The horizontal and vertical planes.
The size and physicality of a defensemen before skill is considered still impacts on the goalie since reach and physicality impact horizontal angles and distance that dictate where shots or attack angles come from. This impacts on the goalie by giving him easier vertical angles to contend with, less horizontal options to contend with, less contact, easier to avoid screens. These factors make the goalies job easier, less fatigue.

Doesn't the fact that your previous example Chara was a (Significantly more skilled.) replacement for Gill in Boston, and Rycroft's subsequent inability to succeed in Toronto with Hal Gill on the team as well, demonstrate that the quality of the defenseman and defensive system is the defining force?
I am far from convinced that defenceman size is relevant at all, but I do think there is good evidence that team shot prevention affects the number of games that goalies play. If you look at all the individual goalie seasons with 70 or more games played since 1983-84 (n=71), 50 of them were by goalies facing fewer shots against per 60 minutes than league average. The average for the entire group of 71 goalies was about 1 SA/60 below league average. Thirty faced a SA/60 rate that was 5% or more below league average, while just 10 faced 5% higher than average.
Looking at save percentages compared to league average gets very similar numbers (51 above average, 20 below average), which suggests that the impact of talent was roughly equivalent to the impact of shot prevention, although shot quality may be a significant factor, particularly in the earlier years in the sample ('80s and '90s).
I also looked at every goalie season with at least 40 games played, and sorted them into four groups based on whether they were above or below league average for save percentage and shots against per 60 minutes. Using the frequencies in each bin from the 70+ GP sample, we can calculate the percentage chance of a starting-calibre goalie playing over 70 games based on those two variables alone:
Save % > LgAvg, SA/60 < LgAvg: 35 / 244, 14.3%
Save % > LgAvg, SA/60 > LgAvg: 16 / 198, 8.1%
Save % < LgAvg, SA/60 < LgAvg: 15 / 165, 9.1%
Save % < LgAvg, SA/60 > LgAvg: 5 / 132, 3.8%
This evidence suggests that team shot prevention is slightly more important than goaltender performance in determining how many games they play. That is, of course, if you accept save percentage as a reasonable proxy for goaltender performance. The shot quality effects in the '80s and '90s were significant for many teams, although typically the correlation suggests that low shots against is correlated with higher save percentages when parity is low. If the goalies on strong defences tended to get a save percentage boost, that would actually strengthen the argument that shot prevention may have a slightly stronger impact on games played than individual goalie performance.
At the very least, these numbers make it pretty obvious that a starting goalie's games played are strongly impacted by his team context. If durability was some separate skill that was unrelated to a goalie's talent or the team in front of them then we would expect to see much less variance based on the two variables being analyzed. This study does not even take into account what is probably the largest factor of all in determining games played, the talent of the backup goalie, or other relevant factors such as whether the team was in a close fight for the playoffs or the difficulty of their travel schedule.
I don't know why the same poster is apparently trying to argue in the same thread both that games played is a good stat for evaluating goalies and that games played are largely determined by the rest of the team, but he's probably closer to the truth on the latter. I personally do not consider games played to be an important factor in my goalie evaluation.

I'd love to see the quality of the backup to all of them listed as well, that's my initial reaction and I don't think there's been much talk of that being a factor.

Size Factor
Let`s take team from the abstract to the actual on ice experience.
Players on a team vary in size and ability. With equal ability the size factor influences reach. A player who is 6'7" tall has a longer reach than a player who is 5'10" tall. Put each at the same spot on the ice in the defensive zone. Stationary, the taller player establishes a larger horizontal perimeter that the attacking team has to penetrate to shoot. Further away from the net the attacking player is, the weaker the shooting angle - horizontal or vertical, to the net. The resulting shots are from a greater distance, less accurate - more likely to miss the net and require less movement or effort from the goalie. Distribute this factor over five skaters with a size/reach advantage over smaller players and the goalie has an even more favourable situation and will be less fatigued playing the game.
A very blatant example of the size factor would be putting an average six year old in the slot in front of a goalie. Barely a change in the angles - horizontal or vertical to the 4' x 6' net that the goalie is defending or his ability to defend it or the effort he has to spend. Put an NHL defenseman the size of Hal Gill in the same spot as the six year old. How much net would be available to a shooter and how much effort would the goalie have to spend.
The statistical analysis that you present about shots and SV% is interesting but is it sufficient? Preventing a goal is the prime objective of defense. This may be achieved by one of the skaters blocking or deflecting a shot or pass. By creating a situation where the shooter has a weaker angle, longer shot, that causes him to shoot outside of the 4' x 6' target. All elements produce the desired result of not allowing a goal but only a few get considered.
Of course the team performance is slightly more important. To be expected. Issue remains what are the elements that impact team performance favourably. Size is one of the key factors that is overlooked.
Which is my fundamental point.

The thing with Luongo is that he struggled when he first came to Vancouver (as in the first few weeks), then publicly asked his defense to stop blocking so many shots, so he could get in the game.

Is there any evidence that a team's tendency to block shots has a negative impact on its save percentage?

There is evidence that Roberto Luongo does not feel comfortable if he doesn't see that many shots. It comes from his own mouth

No, there is evidence that says that different goalies prefer and perform better behind different defense styles though.

Deflected Shots
SV% on deflected shots that are on goal would be revealing.
Also asking why offensive players deflecting shots and screening goalies is an effective tactic.
