There are decent goal scorers in the NHL that for some reason don't get
a lot of power play time. Sometimes their goal streaks can even grow to
three digits, all without a PPG. Here is the list of the longest ones
since the 1942/43 season, the earliest with the reliable PPG data.
Inactive streaks (those that are over, and those that belong to inactive
players) of size less than 5 are omitted to reduce the data volume.
