It would be nice if season high/low information was available for various statistical categories.

This would apply to  league, team and player data

E.g.,   Highest Team Score in the League
           Most Block Shots by a player in the League
           Lowest Turnovers for a particular team
           Highest Points for an individual on a particular team
           
Ideally, this would be searchable while a league is active.

In its simplest form, a summary report would be available for particular statistics.

For progressive leagues, one could also apply an "all-time" scope.
