Soccer is a slow burn where a game is always standing on a fragile equilibrium. Football and baseball are mainly boring because they are turn-based, with long periods of nothing happening between brief action moments.
Basketball is the only dominant US sports that matches soccer in terms of excitement and teams standing on a fragile equilibrium. Of course the NBA screws this up by stretching finals games into 7-game series, capping soccer-levels of excitement derived from winner-takes-all tournaments. It's no coincidence that NCAA tournaments manages to build up so much attention and such a dedicated following.
Baseball I get the sense people watched or listened to some, often while doing something else, and followed the rest in the newspaper or the evening news highlights.
