That was about 14 months ago. Now Lynch has decided he wants to give football one more shot and with the Oakland Raiders. The two teams agreed upon a trade Wednesday, according to Adam Schefter.
But no one can argue that Lynch found retirement boring. By all accounts, he made the most of his time away from the game.
One of his first trips was to Egypt where Lynch rapped while riding a camel and seemed to thoroughly enjoy himself.
Lynch was there as part of the American Football Without Barriers program.
On that same trip, he stopped by Cairo American College, played basketball against a student, dunked on him and went on his way.
Lynch also stopped by the Children's Cancer Hospital in Egypt to meet with kids.
Back in August, Lynch joined his alma mater, Cal, in Sydney, Australia where the Golden Bears played a game against Hawaii. Lynch even put the pads on and practiced one day.
This year, as part of a promotional campaign for Skittles, Lynch traveled to Houston, Scotland.
Asked about kilts that the locals were wearing, Lynch said, "I don’t know about that. Where I’m from, we don’t wear those."
Back in the U.S., he spent time in his hometown of Oakland with former President Bill Clinton.
And later, he joined Cal once again, this time enthusiastically driving a golf cart around the field (video above) before a game and nearly hitting some students.
Lynch accomplished quite a bit during his short retirement stint, but apparently he missed football. He'll be on the opposite sideline of his former teammates when the Seahawks play the Raiders in the preseason.
