So I went and read the definition of "playoff" in several sources and Dutch is correct. It can be one game or a series of games. I'm not sure why people feel that they can use their perception to argue facts. You can say that you (and all your friends) believe that in essence 2+2=5...but it doesn't change the fact. A table can have one leg, two legs, 4 legs, 6, 8, etc...it's still a table. You can't make up your own definitions. So then, if by definition, a playoff can be a game or series of games that determines a champion, then the only thing the NCAA is doing next year is expanding the playoff.
You didn't use the full definition. It can only be
one game to determine the winner if there is a tie. That means overtime is a playoff by definition. Plus, you picked from the secondary definition and not the primary which is:
a series of games that is played after the end of the regular season in order to decide which player or team is the champion
Since you're using the secondary definition which is "a
game or series of games that is played to
decide the winner when people or teams are
tied" you have to pay attention to the portions in bold. That means if you do a single game and teams are still tied (win loss record), there has to be more games to eliminate the tie...it's part of the definition of the word and I'm not sure why you feel you can use your perception to argue facts.
You can say that you and all your friends believe that 2 + 2 ≠ 5....but it doesn't change the fact. Yadda Yadda...so on and so forth.
In other words, you're both right and wrong. You're right in saying that 1 game is a playoff if it results in a tie or is with 2 teams that have a tied record...but we are also correct in showing that if multiple people have the same exact record,
a play-off will mean multiple games to satisfy the second portion of the definition of the word....to decide the winner, a tie cannot be present and thus more games are played until a tie does not exist.
