Underdog doesn't publish a feed we can read, but it does let you export your own drafts — so this reads them from you instead of scraping them from anyone. Upload the CSV and see what you're actually holding across every entry, measured against the ADP board. Nothing leaves your browser.
Underdog: Account → Settings → Download my data. Upload your draft picks CSV, and optionally their rankingsCSV to measure against Underdog's own ADP instead of a redraft consensus. Drop several at once — we sort out which is which, and re-uploading won't double-count. Everything stays in this browser; none of it is sent anywhere or published.
