The "Donkey" Concept

[chymechowder]

1. A .220 hitter swings at a pitch outside of the strikezone and bloops one into rightfield for the game-winner.
2. A QB's pass goes thru a WR's hands to a DB who has an easy return for the difference-making score.

In these examples, do you ever hear the losing team say: "Those guys had no business winning. They don't know what the hell they're doing."

Of course not. Why, then, do so many poker players complain when an improbable play succeeds? Granted, the majority of players aren't crybabies or jerks, but there's enough of them out there.

Moreover, I hear/read these people defend their actions, saying things like: "Hey I realize that's part of the game, but if someone's a donkey I call him a donkey."

I guess my question for these people is: Do you not think that basic sportsmanship has any place in poker? Or do you think it does, but you just don't care?
