Just in case you still are searching for your team's first round playoff schedule, you can find it at NHL.com.
If you have a question about OLN in the first round, let me help you out As I noted about 3 weeks ago, your local carrier will still show the game in round 1 if it was/is scheduled to do so. The OLN feed will be blacked out in the local market. Now round 2 is a different story, and you may not want to read about round 2 coverage in order to avoid putting a jinx on your team.
