rosterOS Best Ball Overlay

rosterOS Best Ball Overlay gives you real-time draft intelligence directly inside Underdog drafts, so you can make faster, sharper picks without leaving the board. It grades available players, tracks roster construction, highlights stacking opportunities, and shows exposure context while the clock is running. Instead of juggling spreadsheets, tabs, and guesswork, you get one live overlay that turns your current roster, draft capital, and player pool into actionable guidance each round.

Install rosterOS if you want clearer decisions in high-pressure draft moments, better structural builds across your portfolio, and a more consistent process from pick 1 through the final rounds. The extension is built for practical in-draft execution: less noise, more signal, and guidance that updates as your room changes. It helps you avoid common build mistakes, spot correlation edges, and stay aligned to a winning plan in real time.
