I might be the only person who thinks this but don’t believe it is length of the game but dead time that is the problem. It is hard for young people, in my opinion to be interested in players standing around all the time. I get frustrated when there is ssssoooooo much time between pitches and nothing is happening. If this drives me nuts as a baseball fan in my 30s I can’t imagine how teens who are meh about baseball feel about it. I’ve never cared about how long any sports games have been to me it’s about the dead that makes it boring.
