San Francisco 49ers general manager John Lynch and new cornerback Richard Sherman shared intimate details of their negotiations to Peter King of The MMQB - among them, a discussion about the Seattle Seahawks' painful decision to throw the ball from the 1-yard line at the end of Super Bowl XLIX.

"I promise you, we won't throw it this time," Lynch assured Sherman.

Sherman was released by the Seahawks on March 9 and the veteran corner entered discussions with the Niners the following day.

In the whirlwind that followed, Sherman and his fiancee shared a four-hour dinner with 49ers head coach Kyle Shanahan and his wife. Sherman represented himself in contract negotiations, and even stepped out of his meeting with Lynch to call other interested GMs.

Aside from the money, the opportunity to stay on the West Coast, and the chance to play for a contender, the 49ers were uniquely positioned to give Sherman something else.

"We had something no other team could offer ... the ability to play Seattle twice a year," Lynch said.

Sherman didn't dispute that aspect of the 49ers' appeal.

"I'm vengeful in that way," he said.

Sherman added, "I love the fan base to death, and I loved playing there. It was such a great opportunity. I helped the organization get to a great place and stay there. But now it's like I abandoned them. People are out there burning my jersey. Come on. I'm not the one who let me go. They let me go. I didn't abandon anybody."

Sherman fought for a heavily incentivized deal that other teams like the Seahawks, Raiders, and Lions weren't willing to offer. One such stipulation will award Sherman $11 million - what he would have earned with the Seahawks - if he plays in 90 percent of the team's snaps in 2018 and makes the Pro Bowl, even if he can't play in the game because the 49ers are in the Super Bowl.

"I don't think any agent in the business could have done a better job of negotiating this contract," Sherman said to King. "As long as I'm content with what I'm making, nothing else matters to me."
