Tom Brady's contract is often considered to be one of the best assets in NFL team building. By taking team-friendly deals for less money, Brady allows the New England Patriots to use their cap space on other players to surround him with.

Brady signed a two-year, $30 million deal this past offseason. His base salary for this season is only $4 million, however, Brady has a $10 million restructure bonus and five incentives are also included.

If the 41-year-old quarterback managed to finish the season inside the top five in passer rating, completion percentage, yards per attempt, touchdown passes, and passing yards, he'd earn an extra $5 million. Each are worth $1 million, but with just three weeks left in the season, Brady isn't on pace to reach any of them.

Last season Brady finished in the top five of all five categories, but in a year of record-setting offenses, the Patriots haven't been among them.

This morning, before their loss to the Miami Dolphins, Brady was ninth in passing yards (3,342), 14th in passing touchdowns (20), 15th in passer rating among starting quarterbacks (96.8), 21st in completion percentage among starting quarterbacks (65.9), and 11th in yards per attempt among starting quarterbacks (7.7).

Today, Brady completed 27 of 43 passing attempts for 358 yards, three touchdowns, and no interceptions.

Next season, Brady will be making a base salary of $14 million dollars with another $5 million restructure bonus. It will be the final year of Brady's contract and he would be 43 years old at the start of the 2020 season.

How much money will head coach Bill Belichick and owner Robert Kraft be willing to invest in Brady beyond next season will be interesting to see.
