@YouTubeTV have you considered adding @NHL and @NHLTVSupport to the lineup? We already have @MLBNetwork (for what that's worth, with their BS blackout rules) and @NBA - so, why not some hockey, too?
While we don't have a timeline for adding the NHL network, but adding new networks to our lineup is something we always love to do. Please fill out the channel request form here: https://goo.gl/BcKWsC . Thanks!
