The New England Patriots reached an agreement on a two-year contract extension for star quarterback Tom Brady. Brady is now under contract through the 2019 season. Brady celebrates his 39th birthday in August, so he'll be under contract until he's 42 years old. Brady is a former sixth-round draft pick Brady is scheduled to cost $15 million against the cap next season and another $16 million in 2017 under his current deal. Coming off another MVP-level season, his base salary makes him one of the league's most underpaid signal-callers after signing a five-year, $60 million contract in 2013.
