Most of the complaints sound like whining from the big markets. Out of the 4 teams in the LCS, the Diamondbacks are the only one that are a true surprise to anyone paying attention, and the Dodgers put up such a pathetic performance in the NLDS that nobody in their right mind would expect them to have won a series of any length against the Diamondbacks. They cobbled together a pitching rotation and then failed to score off Brandon Pfaadt.
The thing about playing 162 games is that it's been a long, long time since April and May. If you ask the Texas Rangers, I bet they would say it's been a long, long time since their inexplicable collapse in August.
And the two defending league champions advanced, both of which returned basically the same teams that won the pennant last year. On what planet is either of those two teams winning an upset???
