I like Jack because he gets the PBP call right most of the time, so I watched it on NESN - I knew it would be on NESN, and noticed that the listing was "Bruins in Two". (I think this was for Game 4, but it could have been Game 3.) Honestly, even if I hadn't known, I would have tested the waters on NESN first. That's my MO all the time for Bruins regular season - check NESN, simply because the odds are better. If it's Charlie Moore and not "Charlie and Moore", flip as fast as possible to NBCSN.
But if I were patient enough, I'd rev up NESNgo for audio, and switch to NBC feed on mute (shut up, Pierre!) for the first round. In the past, I've been relatively calm about the ticker, but it's mutated into something terrible. We live in a world with second screens - nobody wants the score of the Diamondbacks game! And, as long as NBC isn't messing with "Star Sunday" shift length, their graphics are better, IMO - the poop brown to indicate which team is on the PP is ridiculous.
