Sidney Crosby and Mike Sullivan have formed a pretty productive partnership for the better part of six years.
The Penguins have won two Stanley Cups and a few hundred games during their time together -- mind you, lots of other people also have contributed to the franchise's successes during that span -- and they are trying to extend the team's league-best streak of playoff appearances to 16 this season.
But in a little more than three months, they'll be rivals on one of their sport''s biggest stages.
Crosby is the favorite to be Canada's captain for the 2022 Olympics in Beijing, while Sullivan will be the head coach of Team USA.
