Given the depleted state of the roster and the necessary cap reset, Brady would have wasted the last three years of his career. While it is still painful to think about, TB12 leaving when he did to a team with a better roster was a win win for the team and player. The Pats would have been incrementally better for those 3 years, but not in play to win the Super Bowl. The team was able to get started on the rebuild sooner. Today we would be in the exact same place as far as QB goes, a mediocre draft position, with a less talented roster and no cap space. Ironically only BB would have benefited if Brady stayed because he would have more wins for his pursuit of Shula.
