Season-long fantasy basketball is unique. In modern days, the season-long format is less popular than the daily format. With production less variable than other sports, the key to success in fantasy basketball in any format is getting the right stars on your roster and continuously surrounding them with the players seeing minutes, usage, and opportunity.
The problem is that the top level of the NBA has never been deeper, but it has also never been less reliable. Seventeen players averaged at least 45 fantasy points per game in 2020-21, but only nine of them played at least 60 games.
