Everything happens in the draft

Best ball has no waivers, no start/sit — you draft a team and it auto-optimizes each week. That makes the draft the whole game, and Roster Locker's draft help is free and unmetered:

Value reads — who's falling below their range and worth a pick now.
Roster construction — position balance and how many at each spot for best-ball scoring.
Stacking — pairing correlated players to raise your ceiling.
Live tracking and on-the-clock alerts so you nail every pick.

Draft best ball on your platform

Roster Locker's free live-draft help runs on Sleeper, MyFantasyLeague, ESPN and Fleaflicker best-ball and redraft drafts. Connect once from the platform pages and you're set.
