I'm all for that. I think it is super disgusting and I hate how high school and college age baseball players think it is cool.
But you know why they think it is cool? Because you look at all the major leaguers and what are a lot of them doing? Interesting I just talked about role models in the Masters Thread, athletes CAN be a huge impact on a lot of young people even ones that aren't little kids. I hate it when I turn on a game and they are picturing a player talking about what a great player he is, and there he is just dipping away in front of all the kids watching.
No need for it to be allowed while they are playing, if they want to do it they can wait til later. It is of no benefit to the game. I agree go get some gum, it is a lot better for you long term. You don't see basketball players running down the court with a dip in, you don't see a teacher or a secretary or whatever else with it, why should baseball players be allowed to do it at work? On your own time, do whatever you want to harm yourself. But when you are representing your company or team or whatever else's image, you don't do that stuff IMO.
Players will never allow it cause so many do it, but I would be all for it!
