What I remember about Brodeur is that - while he was not a butterfly goalie as Roy/Allaire had not set that in motion in time for Brodeur to really adopt - he was ahead of his time in being what I would term a blocking goalie, reading the play to be in the correct position to stop the puck, rather than reacting to the shot (see Fuhr).
As for save percentage during 83-87, we sucked - and we played a lot against a guy named Wayne in his prime. Again, my memory is that Brodeur provided goaltending for many seasons that allowed a team to be in a game - unless that team really sucked.
Which we did.
But yeah, I agree with Jyrki21 that memories of a brief peak overshadow the memories of other play. Really, I prefer just to remember '82, '89, '91-'94 from that last century.
