Your best lineup, every week
League Loom lets Claude or ChatGPT optimize your fantasy lineup from your live roster, automatically flagging byes, injuries, and rough matchups so you never start a player who can't play.
Three players need attention before lock:
Swap McCaffrey for your FLEX bench RB, slide in a replacement for Chase, and hold a backup ready if Nacua sits.

A lineup optimizer is only useful if it knows who's actually on your bench and who's hurt. League Loom pulls live roster, injury, and bye data from your real league, so the AI's advice reflects this week, not a stale snapshot.
