I haven't watched a lot of the National and American League Divisional Series on TBS, but I have read the reviews.
They're universally awful.
I should note that the reviews were written by people who have never been behind a microphone. Errors during three hours of live, unscripted television are inevitable. No one's perfect, especially when you're flying without a net for hours at a time.
Having said that, TBS probably could be doing a better job.
Lighten up. It's only a game.
