Tom Brady is the greatest quarterback in NFL history. His accomplishments on the field are unmatched and he holds a seemingly endless list of NFL records from his career with the New England Patriots and the Tampa Bay Buccaneers. This includes career passing yards (84,520), touchdowns (624), wins (243), and Super Bowl victories (seven).While his undeniable greatness on the football field has cemented his legacy in NFL history, Brady hasn't always avoided controversy. He has made headlines over the years for being mixed up in relatively controversial situations.Here are five such examples.#1 Miami Dolphins ownership scandalMiami Dolphins owner Stephen RossThe Miami Dolphins were involved in one of the wildest rumors during the 2022 NFL offseason. They were allegedly recruiting Sean Payton to be their next head coach and Brady to be their quarterback. Brady was also apparently in negotiations to receive an ownership stake in the franchise.The NFL determined the rumors were true during an investigation and punished the Dolphins for tampering with players and coaches under contract with a different team. Owner Stephen Ross was fined $1.5 million and suspended for the beginning of the 2022 NFL season. The Dolphins were also forced to forfeit two draft picks.#2 Tom Brady's retirement and NFL returnTom Brady at Super Bowl LVBrady made a huge announcement during the 2022 NFL offseason.
