You couple on field identity to personality and lifestyle, so that fan interest extends beyond the white lines. And you use that to build the following for players in the sport. Young people now watch players more than teams and one of the problems MLB has had is they don't market players.But how, exactly? To market someone by lifestyle and personality, they must either 1) have so much attention drawn to them for other reasons that people care about their lifestyle/personality, or 2) their lifestyle and personality themselves are so interesting that even non-fans want to follow them. 2) is the route that, for example, the Kardashians took. Baseball players would be 1). But I just don't see how you get ordinary people so interested in the lifestyles and personalities of baseball players that they'll actually watch the games.
Exactly how do you do that in a significant way? The very nature of baseball simply doesn't give nearly as many opportunities for that kind of thing as does basketball or football. It's a more sedate game in terms of the game itself.
I just don't see that moving the needle very much in terms of fan interest in watching games.
Baseball doesn't need social media followers -- It needs fans to go to the games or watch them regularly on TV. The kind of stuff you're describing might help an individual player build a niche instagram following. I don't think it makes more people actually watch baseball. Why should they? They can just get the bat flips on their social media feeds, and skip the boring (to them...) games.
ETA: And there's no need to take gratuitous shots at another poster who isn't in this conversation.
I am a JJ Reddick fan because I watched him play at Duke. I will tune into an NBA game here or there to see him play, other than that I do not watch the NBA at all. But I became a fan of JJ at Duke and have followed him (hit and miss) ever since. The NBA gets one more set of eyes occasionally then they would have otherwise. Makes no difference what team he is on, in fact there are years I have no clue what team he is on, but if one of my friends is going to a game and JJ is playing I probably tag along. And they follow the sport, and know I am a JJ fan, so they know when to invite me.
But that is not baseballs way, because "no player is bigger than the game itself" is one of the dogmas. So you have to market the name on the front of the shirt not the back. But in this day and age, that doesn't captivate young fans and build a following out into the future.
I remember Billy Martin and Earl Weaver still, because of the battles with the umps. Great theater, and one of the things that helped bind me to baseball. But it was their personalities, not the team they managed. However, my interest in them and what they were up to helped solidify my interest in baseball. And now, I watch baseball as a pro sport exclusively. Have no interest or will I give up the time for any other than UFC.
You catch young peoples attention through social media these days, and baseball DOES NEED many more SOCIAL MEDIA followers.
