My list of complaints about NESN's Red Sox broadcasts should be well-known to readers of this blog. (If not, click the nesn tag.)
You probably share at least some of them. Missed pitches during every single game, consistently shoddy camera work, mediocre-to-poor announcers that often will not shut up about absolute nonsense (both game-related and not) while ignoring chances to provide genuine insight, a flood of advertising during the game, guests in the booth promoting other NESN shows ... (And holy shit, remember this?)
In short, NESN has trouble (and has always had trouble, at least since 2003, when I began watching games via MLBTV) performing the most basic tasks involved in broadcasting a baseball game.
