How about the mental strength to be able to work through jams without pep talks, how about putting in the work before a game to know the game plan for a hitter or situation without a pow-wow on the mound, how about the athletic ability to throw more than a pitch every two minutes, how about showing mental toughness over the opposing player to stay more focused than the other within a shorter timeframe, how about working through your nerves in tight game moments? etc etc. —That's exciting.
Pulling the plug and walking off the mound because the build up is too much for the pitcher, catcher or manager lets all of the air out of the balloon. You're in the middle of the game, so face the music and try to out-duel your competitor in the moment for our entertainment.
