• Sign free agents and negotiate trades with other managers

SIMULATOR
Pick any two teams and simulate:
• Quick Sim — one game, instant result
• 7-Game Series — a full head-to-head series
• Playoff Bracket — run an entire postseason, play-in through the Finals
Mix and match current rosters with classic-era teams for dream matchups history never gave you.
