There are some sports feats that have been accomplished so rarely that every occurrence of them can be tracked… unassisted triple plays and perfect games in baseball, for instance.
What are some such feats that can be hypothesized but have never actually happened?
(Note that this question can be trivially answered by taking any numeric record and increasing it by one… ie, no one has ever scored 101 points in an NBA game, no one has ever had a 57 game MLB hitting streak. So I’m looking for things that are absolutes, either they happened or they didn’t, nothing with a greater-than-some-number component.)
For instance, has there ever been an NFL game in which all the scoring was in the form of safeties? Has there been a game-ending unassisted triple play in the MLB? A savage swat block of a shot in the NBA that flies all the way down the court into the other basket?
