Hear a lot of people say this and while I’m certainly not saying it’s wrong by any means, just curious as to why you think so?
There is a certain charm to the radio broadcast -- the announcer(s) can describe the weather, backdrop of the sky, the uniforms the players are wearing, the lighting in the stadium, the colour of the field...and it's like they are painting a picture in which you can envision it without even needing to see it.
The sounds of the game are really captured as well, from the crack of the bat to the umpire's calls. There are even times you can hear the concession worker going up and down the aisles selling their products in between it all.
There is just something about a radio broadcast where it allows the game to "breathe" that no other sport can capture.
