4. Baseball would become dramatically more violent.
I’m not 100% certain of this, of course. But I am probably 75% certain. Right now, we don’t tend to think of baseball as a contact sport. There IS contact — plays at the plate, double-play meetings at second base, the occasional hit-by pitch and ensuing bench-clear — but it’s mostly tangential to the game. Football, meanwhile, is violent at its core. Or anyway, that’s what we think now.
Except — baseball was extremely violent in its early days. And I think that if the game was played just once a week, if you faced each team only once or twice a season, if every game was critical, there would be a lot more violence in baseball. Collisions at the plate would be intensified. Nobody would concede the double play without really taking out the fielder. Pitchers would be much more likely to send message pitches. And I think you would probably find violence where there is none right now.
Here, think about it another way: What would happen to football if there were 162 games in a season. It’s unimaginable the way football is played now. Players could not survive. But if there was a 162-game football season, football WOULD NOT be played like it is now. Not even close. I think the violence would drop to almost nothing. It would become a glorified game of two-hand touch. Big hits would almost never happen — maybe in the playoffs. There would be less coaching. There would be less intensity. Football would HAVE to evolve that way for survival.
