Tom Brady's new extension saves the Buccaneers $19 million in cap space and means he's nearly guaranteed to reach his goal of playing until 45

• Tom Brady agreed to an extension with the Tampa Bay Buccaneers.
• The move helps the Buccaneers to save $19 million against the cap this year.
• It also all but guarantees that Brady will accomplish his goal of playing until 45.

Tom Brady's move to the Tampa Bay Buccaneers was a smashing success.

In his first season under center in Tampa, Brady led the Buccaneers to a Super Bowl win at the age of 43. After signing a contract extension with the Bucs on Friday, Brady is poised to do it again ... and again.

According to ESPN, Brady's new deal is a four-year extension that voids a one-year extension that he already had in place. The move is a budgetary one for the Buccaneers, as it will save the team $19 million in cap space this season - an important advantage in a year that the cap is shrinking.

But the deal also means that Brady will be in Tampa at least through the 2022 season, meaning that he will likely complete his goal of playing until he's 45 and possibly go even further.

Brady celebrated his extension on Instagram, telling fans he was ready to chase after his eighth Super Bowl title.

Brady has been clear about his goal to play until he was 45 for some time. As far back as 2015, Brady had hinted at the goal, and through the past six years - during which he's added three more Super Bowl wins to his record - has doubled-down on his mission. Brady's trainer and business partner Alex Guerrero has even teased that he could play until he was 47 or 48.

Brady's goal has even inspired other players, such as Seahawks quarterback Russell Wilson, to pursue the goal themselves.

While the Buccaneers' immediate incentive for the extension is the cap relief that the move provides, after the stellar season Brady had last year, Tampa Bay is surely happy that their new quarterback seems ready to make his career goal come true.
