Figure 3

Regression model examining fights per game and seasonal success (measured by total points achieved per season divided by games played). When examining all teams over all seasons, a significant and inverse relationship existed between fighting and the seasonal points earned per game (coefficient = −0.16,  < 0.001, R² = 0.04). Each blue diamond represents one team during one season.
