Metrics — ALOFT history

ALOFT metrics and records, by coach and by season. Points tables are era-labelled; rates show denominators. Keeper metrics are the headline set.

Keepers per season

CBS keepers from message-board declarations; Sleeper keepers from draft `is_keeper`. Keeper count is per kept player, not per coach.
