The season's biggest upsets by today's SP Strength Index, and the teams that keep knocking off better opponents.
An upset here is a win by the team the SP Strength Index rates lower today, after a small home edge, by more than 3 points. The chance shown is how often a team that much weaker wins. Ratings are this week's, so an early-season surprise by a team that turned out good fades from the list.
