Fantasy Lineup Optimizer

This pulls together matchup data, injury reports, weather conditions, and Vegas lines to help you make sit/start decisions across NFL, NBA, MLB, NHL, and soccer. It gives you confidence levels with each recommendation, which is honestly more useful than most fantasy tools that just spit out rankings without context. You feed it your roster dilemmas, and it breaks down the reasoning behind each call rather than making you guess why Player A is ranked above Player B. Works across all major fantasy sports, so you're not juggling different analyzers for different leagues. Best for when you're stuck between two similarly ranked players and need actual data to make the call.
