And cricket fails all three requirements! 
Go to India and say that. Half a billion people will take your head off with a well-directed bouncer.
You threw me off with your inclusion of “soccer,” Rik. Not hugely American, surely? Anyway, I’ll stop hijacking now.
Baseball may be a game about suspense rather than action (generally-speaking), but I disagree that it’s a game about fine adjustment any more so than any other team sport. Regardless of regulations on the size and shape of a playing field, all stadiums and locations are different across all the sports. Teams play differently because in some arenas the ice is faster, while in others the boards give up funny bounces of the puck, while in some stadiums the wind will knock your kick-off down and throw your passes wide, or there might be a crowned field that leads to balls rolling off for throw-ins more than in other places. There’s a tremendous amount of nuance to the playing surface and location for all sports. This is not something unique at all to baseball.
Further, I disagree that you cannot be as precise running down a basketball court as you can on a baseball diamond. Sure, a pitcher is looking at putting a ball in a specific location, but he’s got all the time in the world to aim and throw, while a basketball player, or a hockey player or football player, has to hit a small mark while in motion and anticipating the movements of up to 21 other people. No one sport of those mentioned can claim to be more precise or fine in its adjustments.
And even further, there is just as much need to fine-tune a strategy in hockey or football or basketball or soccer to account for who your opponent is, what sort of strategy he or they will play, what the conditions are, what your own strengths are, etc. Coaches spend countless hours going over video of other teams, analyzing their strengths and weaknesses and deciding how they are going to play that opponent based on a number of different factors. Baseball is not more fine-tuned than the others.
I will agree, though, that over the course of a season in baseball luck should be less of a factor simply because the length of the season - it shoud even out the luck for all sides.
I actually said:
Bloding mine. I love baseball. It’s the first sport I learned to play (and I’m Canadian). I could out-hit and out-throw everyone my age when I was growing up, but we couldn’t afford to play in a league so I never got to develop it. My point being I love the sport. I do find, however, that the season is far too long to be motivated to care and the traditions that have led to there being two different leagues with different rules and parks with such radically different shapes makes it a bit hard to understand. There’s no rational reason for there to be these rule differences or parks shape differences other than “that’s just the way we’ve always done it”. That’s fine, and baseball fans can hang on to those traditions forever. But it’s not rational (though certainly not an objectively bad thing).
I wouldn’t be surprised to find that baseball managers spend the least amount of time in sports on strategizing and preparing for their next opponent. Sure there’s strategy in baseball, but what are we really talking about? The manager sits down and strategizes for how long for each game, an hour?
If baseball games were once a week, I doubt that managers would spend every waking moment of their 20 hour days preparing for the next opponent. NFL coaches would do this every day for as many weeks as you give them between games. They have an endless sea of details to analyze and strategize. The different venues (weather) are the least of their worries.
True, managers don’t spend that long to prepare for a particular game, but that is because they have a large group of people who do it for them… Hence the term Manager. In baseball, the teams send advance scouts to watch the team they will be facing in the future, they make reports, and send it to the players and managers who then use that information. Also, the manager strategizes mainly for a team, not necessarily for one game. A normal series is about 3 games, and strategies made will normally work for all three games.
All sports have that. It seems that of all the sports, the cushiest top job with the most free time and the least amount of prep work is baseball manager.
