Every athlete has a best season. They could be a superstar or just a regular depth player, but each one has a season in their career that stands out among the rest.
Maybe it comes in their first two or three years and is considered their “breakout” season, or maybe it comes later in their career during a championship run. Either way, there’s that one season that the player is known for.
The same can be said about sports teams. There is that one season that simply outdoes all of the other ones throughout the franchise’s history.
