During the Olympics they will put curling and biathlon on, like, CSPAN12 or that channel that's a 24/7 infomercial about suing companies because you once used baby powder. I'm sure they'd so something similar with baseball playoffs.
I don’t see why it wouldn’t draw similar TV numbers as last year’s World Series depending on who is playing. Sunday Night football already outperforms the WS head to head. Now, I do think interest in MLB could wane this season with the late start and no fan attendance, but I don’t think playing deeper into the calendar will have much of an effect.
I know there are a million TV channels and a lot up in the air but another thing to remember is the TV contracts. The National TV broadcast channels for postseason TBS, ESPN, FOX, FS1 may have other commitments in November. A ton of moving parts here.
