The Opponent Strength Index (OSI) provides a preseason snapshot of the overall strength of schedule for SSAA 11-Man programs heading into the 2025 season. The higher the OSI rating, the tougher the schedule a team is expected to face. As the season unfolds, the OSI will update weekly based on results, reflecting both performance and the quality of competition.
