Your Best Ball Portfolio, your data
Exposure alone doesn't tell the full story. rosterOS layers value, structure, and correlation so you can evaluate your portfolio like a real decision system. Your draft history is your competitive edge. rosterOS is designed so uploaded CSVs are processed locally in your browser and not uploaded to rosterOS servers.
Features
-
See the full state of your portfolio in one place, from total draft volume to overall exposure shape and performance signals. Instead of checking multiple views to understand where you stand, the dashboard gives you a clear operating picture you can act on immediately.
-
Break down every drafted player with the context that actually matters: how often you are taking them, where you are gaining or losing value versus ADP, and how those decisions trend over time. This is where portfolio discipline becomes measurable, so you can double down on edges and correct leaks early.
-
Review each draft as a complete roster construction, not just a list of names. You can evaluate structure, identify stack relationships, and compare team-building patterns across your portfolio to see whether your draft process is consistent, diversified, and intentionally built.
-
Track how your portfolio is shifting in real time through clear trend and distribution views. Concentration risk, positional drift, and overexposure become visible early, giving you time to adjust before those small deviations compound into expensive mistakes.
-
Study market movement over time and pressure-test your timing decisions. ADP trend review helps you understand whether you were ahead of the market, late to a shift, or consistently paying a premium, so your next drafts are grounded in sharper timing and cleaner execution.
