If trying to find on-field competitiveness, one could find every team's average OPR percentile since some year, and then take an average of that for every regional which would give a regional difficulty rating. Then the standard deviation of OPR percentiles could be generated for said event which would give an idea of how closely matched the teams are.
It wouldn't be perfect by any means, but it would be interesting to see.
