I'm looking for one replacement in a league that allows only managers with a rating of 900 or higher. Needless to say that it's very balanced with a high level. For a replacement, I can make an exception of course.

Yahoo, free, H2H daily, redraft. 12 teams, 16 players per team.

This is the roster: https://hockey.fantasysports.yahoo.com/hockey/3734/11

And here are the league settings: https://hockey.fantasysports.yahoo.com/hockey/3734

I think you should be able to see it, if not please let me know and I'll screenshot it
