The Zetterberg Era
Ball Hockey Sucks
The NHL had divisional playoffs for years.
A lot of those banners hanging in the rafters are from winning divisional playoff series I believe.
Essentially what we have now is a division playoff -- except for one wildcard.
I think you are correct, trouble remembering now, seems so long ago. But pretty sure the banners were for winning the first two rounds and getting to the Conference Finals.
