10-Game Record of Recent Stanley Cup Champions
The Penguins beat Florida to tie the 1984-85 Edmonton Oilers and 1992-93 Penguins for the most points after 10 games by a defending Cup Champion.  Note, of course, that this year's Penguins won three of their games in a shootout, something that teams in the 80s and 90s couldn't do.
