League settings: points per stat
Enter the points your league gives - copy them from Yahoo: League → Settings. Blank = 0. Nothing is pre-filled. Values are saved in this browser and used for fantasy points on every Players page. Later, once Yahoo approves API access, this can be filled automatically from the league.
Skaters
Goalies
GAA and SV% are left out: Yahoo points leagues score the goalie counting stats (its default points setup uses W, GA, SV, SO); I could not confirm GAA or SV% as points stats. L and SA are here because Yahoo can offer them; a box left blank scores nothing.
Taken in my league: 0 players (managed on the Rankings tab).
The link carries the scoring, your Taken-in-my-league list (Rankings tab) and your ranking weights in its address (after #), so opening it on another device loads the same things. Nothing is sent to any server.
