So between 1996 (first full season of Wild Card) and 2014, the most wins a non-playoff team had in a season was 96 by the 1999 Reds, but they got to play a 1 game playoff and lost, so it was almost the same thing as the current format. Other than that, 3 teams won 93 games and didn't make it, and the average number of wins for the best non playoff team each year is 89
