Leverage Averages, also known as Lens Averages, is a unique metric that has been used to rank teams in the French Ligue 1. This method takes into account both offensive and defensive performances of each team during their season. The lens averages include key statistics such as goal difference, shots on target, and clean sheets.

In the 2020-21 season, Lens was one of the standout performers in the French Ligue 1. Their average of 15.2 lenses was significantly higher than the rest of the teams in the league. This indicates that Lens had an exceptional performance across all aspects of the game.

The team's strong defense played a crucial role in their success. They conceded only 28 goals throughout the season, which was the fewest in the entire league. This low number of goals allowed them to focus more on offense and produce high-quality performances from their forwards.

Offensively, Lens scored 64 goals in the league, placing them second behind Paris Saint-Germain. Their ability to create scoring opportunities and convert them into goals was impressive. The team also had a high shot conversion rate, with 79% of their shots being on target. This suggests that they were able to take advantage of any defensive mistakes made by their opponents.

Overall, Lens' strong defensive record and high offensive output earned them the title of the best team in the French Ligue 1 based on their lenses averages. Their success can be attributed to their well-coordinated strategy, disciplined playing style, and outstanding individual performances from their players.
