I think you're confusing luck with low percentage plays. physics, skill and cause & effect. The 70 foot shot doesn't go in by accident. The player has to throw it perfectly. It's a low-percentage play for sure...but it's not some quirk of nature that makes the ball go in. And a baseball that just skips off the foul poll isn't luck... that's where the guy hit it. Those outcomes are every bit as real as the mundane... just not as common. They are perceived as "luck" because they skirt the boundaries...they're not easily predictable.
Guys slip on every play... balls get tipped... there are bounces... every sport is defined by these moments. (most of them are more subtle and go unseen) They certainly look more awkward and unusual than the common play, but they are still an integral part of the game. (and the real world) Of course if you're a hard core KFz protege that may be tough for you to grasp. (Life and sport is defined only by the simple and routine). But that's not the real world.
Many people greater than me have said it this way "good teams, make their own luck".
