This particular game coverage was better than most nowadays. But ...
I grew up with the classic: you had a play-by-play announcer and one or more color commentators. Sure, when there was rapor (natural or forced) the p-b-p would interact but there was never an issue as to where the focus of that person was: the game. When someone might go off on a tangent or some story they would cut off, even mid-sentence, when something happened that needed to be reported.
That started changing decades ago, but the degradation was slow. Lately it's disintegrating; games in all sports are becoming unlistenable.
I don't know whether networks focus-group or poll on this stuff, but I have to believe they'd learn pretty quickly that people watch games for the games and not this mindless irrelevant chatter.
