You should have asked the series everyone anticipates the most ASIDE from the one involving their team. It would not have been biased.
For example, I will not pick the Habs vs. Rangers series as the Canadiens are my team. The series I anticipate the most is the Leafs vs. Capitals one. It will be fast, exciting, and I am expecting the Leafs to surprise a lot of people.
Except for that one, I will principally follow Chi vs. Nash (for the Subban element) and Edm vs SJ (for the McDavid element). The most boring series should be Boston vs. Ottawa, but I will watch some of the games as I adore the first round of the playoffs.
