The immediate success of goaltender switches for the Washington Capitals and New Jersey Devils during the Stanley Cup Playoffs highlights the importance of being able to change course in a series.

History shows this to be the case.

VANCOUVER -- The names on the list joined by Roberto Luongo on Thursday say it all:

Patrick Roy. Martin Brodeur.

To the uninitiated, the preoccupation with post play among NHL goaltenders and those who analyze them may seem at best disproportional to the actual demands of the position and at worst an unhealthy obsession filled with odd names.

There is a Post Lean VH (which stands for Vertical-Horizontal), Dead-Arm VH, the Reverse-VH, with multiple options for skate placement, Overlap, and even a Reverse-VH Overlap.

Some might think it's overkill.

So much for talk about the end of shorter goalies in the NHL.

Judging by the height of goaltenders being drafted into the League, and currently making headlines, it might be tempting to think a goalie measuring 6-foot or under were becoming extinct.

New York Rangers rookie Alexandar Georgiev is the latest in a line of Russian goaltenders to turn heads in the NHL.

He is 3-2-0 with a .929 save percentage in his first six NHL games, including a win against the defending Stanley Cup champion Pittsburgh Penguins on Wednesday.

The most impressive part of Alex Ovechkin scoring 600 NHL goals might be how many of them have come from his signature shot.

VANCOUVER -- Jussi Parkkila is making history this season with the Colorado Avalanche.

The 40-year-old native of Tampere, Finland, is the first European goaltending coach to work in the NHL without any playing experience in the League. 

The Philadelphia Flyers sent goaltender prospect Carter Hart back to Everett of the Western Hockey League in the fall with simple instructions.

VANCOUVER -- Finding a goaltender before the 2018 NHL Trade Deadline goes beyond one team having a need and another having an excess. Fit also matters.

That's not to say there are any definitive rules about how a certain style of goalie will fit behind a specific defensive system or style of play. There are few absolutes in goaltending, and goalies adjust their approach to fit different scenarios.

It wasn't that long ago that a big rebound meant a bad rebound. That's no longer necessarily the case.
