This Stanford win over California earned 7.17 ranking points because it was a convincing 21-point victory (31-10) in what appears to be a conference rivalry game, demonstrating clear dominance over their opponent. The point total reflects both the substantial margin of victory and the competitive context of the matchup, though it's not the maximum possible points, suggesting California may not have been highly ranked or the win occurred in regular season play rather than a playoff/championship setting.
