Initial reports have the extension worth four-years, $134 million with $110 million guaranteed, per ESPN's Adam Schefter.
Goff has flourished the past two seasons under Rams Coach Sean McVay, being selected to the past two Pro Bowls.
McVay has solidified himself as an offensive mastermind after he installed a high-scoring scheme that powered the Rams to consecutive division titles and their first Super Bowl appearance since the 2001 season. "Jared wants to be a Ram for a long time, we want him to be a Ram for a long time, and we will continuously try to work to make that happen".
"I think what's really special about him is the way that he's wired mentally", McVay said about Goff in June.
Over the past two seasons, Goff completed 63.6 percent of his passes with 60 touchdowns against 19 interceptions.
Goff doesn't turn 25 until October, and he has been humble about his abilities and expectations despite finishing fourth in the National Football League with 4,688 yards passing past year. The Rams starter's record-setting guaranteed money narrowly surpasses the $107.8 million guaranteed Carson Wentz was given earlier this offseason in his extension.
Now he won't have to.
The Rams have tied up the most important elements of their NFC-winning core over the past year. It's not a contract year for the Bears quarterback, but Trubisky is playing for a big payday that's only increasing as his agent sets new records. This is good news for Los Angeles, who will now have all their key players under contract for the next few years.
The Rams will open the regular season against the Panthers in Carolina on Sunday.
