You don't think asstros-dodgers would pull ratings? With all the dodgers getting a chance for revenge storylines there would be. Or Houston gets a chance to get rid of the cheaters label by beating the dodgers again.
Sigh.
TV people don't see names so much as they see regions. East Coast-West Coast is perfect, in that the formula has always been get the most eyes on a particular product. Splitting the Coasts is perfect in their view for this reason.
I do not hold with their reasoning, believing that the more compelling matchup will draw viewers regardless of regional affiliation. Baseball is a shrinking audience, and they should concentrate on holding their core viewers rather than pandering to those who don't care.
As to the "cheaters" crap, the Dodgers were just as, or more, guilty than the Astros in 2017. The final games of that Series were in LA, where the Dodgers had their home field apparatus to their advantage, while the Astros did not. Yet, the Astros
somehow prevailed. In subsequent years, the Astros managed to make the Playoffs with the foul minions of Manfred's MLB sniffing around, and also after hanging the goat horns solely on them for "cheating" even though the Red Sox, Yankees, Dodgers, and others were doing the same damned thing. MLB just didn't want a League-wide scandal, so they blamed one franchise and pretended that nobody else did anything wrong.
