Yes, the standard line from stats people was that Marty's puckhandling surpressed an average of 1 shot per game. However, in the HOH Top Goaltenders project, I posted why I think that underrates his puckhandling:
"I understand the math behind the "Brodeur's puckhandling stopped about 1 shot per game more than an average goalie" - you compare the number of shots he faces vs his backups. But that just seems too low to me. Are you adjusting for the quality of competition?
Just looking at Brodeur's 4 Vezina years - he only failed to appear in 25 games between all 4 seasons.
These are the teams where his backup played the whole season, their overall spot in the standings, and offense based on goals. (Where does one find team SOG rankings?)
2003: Lightning (12, 13), Predators (23, 28), Leafs (9, 8), Leafs (9, 8), Ducks (11, 22), Sabres (26, 25), Flames (22, 27), Penguins (29, 26) Sabres (26, 25)
2004: Leafs (5, 4) , Penguins (30, 22), Capitals (29, 27), Penguins (30, 22), Capitals (29, 27), Penguins (30, 22), Thrashers (21, 13)
2007: Predators (4, 4), Bruins (23, 23), Capitals (27 , 19), Islanders (17, 12)
2008: Panthers (22, 20), Islanders (27, 29), Penguins (4, 7), Capitals (15, 9), Bruins (13, 25)
- The average team his backups faced was 20th in the standings
- The average team his backups faced was 18th in offense
- 16 of 25 (64%) of the teams his backups faced were below average in the standings
- 16 of 25 (64%) of the teams his backups faced were below average offensively
In my opinion, your estimate underestimates the effects of Brodeur's puckhandling advantage over other goalies in two ways:
- It doesn't take into account the fact that his backups faced teams that were below average both overall and offensively
- It doesn't take into account the puck possession and shots for created by his puckhandling. Brodeur was a vital part of "The Trap." The trapping skaters would prevent the opposition from skating the puck into the zone, leaving a dump-in the only option. When Brodeur killed the opposing dump in, he not only killed the ability of the opposition to control the puck in his own zone, he created an opportunity for his team to control the puck in the opposition zone. The Devils of the era did not have a lot of skilled goal scorers, relying instead of volume shooting to score goals. To put it statistically, a goalie who is excellent at puckhandling should improve the Corsi ratings of all the skaters on his team, especially without the trapezoid."
That project was done in 2012. Since then, we had a couple seasons of an aging Brodeur splitting time with Cory Schneider back when Schneider was good (sigh). And frankly, the difference in team territorial play was night and day.
