An era has ended in New England. On Tuesday morning, Tom Brady announced on social media that he will not be returning to the Patriots, ending a 20-year stint with the team. His announcement shocked Patriots Nation and shook the NFL. The 42-year-old has not yet announced where he will go, but we know his partnership with head coach Bill Belichick has run its course. 

With New England, Brady went to nine Super Bowls, winning six and being crowned the MVP of four. After being drafted as the 199th overall pick in the sixth round of the 2000 draft, TB12 went on to become one of the greatest quarterbacks of all time.

Now, Belichick and company will try to prove they can win without the quarterback, and vice versa. After two decades, Brady has left quite the mark on New England, and in all of the NFL, and with his announcement came many congratulated him on his career so far and wishing him well in the future.

"Tom was not just a player who bought into our program. He was one of its original creators. Tom lived and perpetuated our culture. On a daily basis, he was a tone setter and a bar raiser. He won a championships in three of his first four years on the field and in three of his final six seasons, while competing for championships in most every season in between.This is a credit to Tom's consistency and what separate him. He did not just perform. He won championships over and over again. Tom and I will always have a great relationship built on love, admiration, respect, and appreciation."
