Maybe the broadcasters don’t see these examples as violations. If that’s the case, they should say so. But if they do see something, they know violates the protocols (like spitting or chewing tobacco), the broadcaster should single out that player. They should also ask, out loud, why one of the umpires isn’t warning a player to stop spitting. Instead, what we usually hear is a Pity Party, a voice that reminds us how certain habits are hard for players to break.
