One zen master was Richie Allen, who never complained to umpires, I remember reading stories about this as a kid. Steve Garvey was pretty mellow. The one player I always admired, and who carried himself in a classy way, was Johnny Bench -- in fact, I rate Bench as one of the best players I ever watched, and his fellow catchers always said that, by far, he had the best technique behind the plate.
Current player: Buster Posey seems like a guy that won't ever get thrown out of a game.
Nice point about Bench! He pretty much broke the mold for catchers!
That's remarkable about Richie (Dick) Allen since he had to endure a lot of terrible racism from fans!
