NHL Game 7 history

There have been only 120 of them ever played (one last year - won by
some guy named Roberto Luongo).

As best I can tell, Patrick Roy has played in the most 13, but won
only 6.

Among current legends, Brodeur has played in 8, winning 5.

I can't give you much more on an individual basis but here's the all-
time game list with winners listed first: (thanks whowins.com)
