LegUp Sidekick
Simulation-driven dynamic best ball rankings that reorder after every pick
About LegUp Sidekick
The Sidekick is a browser extension from Pat Kerrane's Legendary Upside (LegUp). It re-ranks players after each pick in Underdog and DraftKings drafts. Its recommendations come from week-by-week player simulations built with ShaidyAdvice, which account for correlation and weigh early-season against late-season scoring. A cheaper LegUp tier includes the Kickstand overlay, which adds on-the-clock alerts, stack and bye tags, and exposure display.
