The veteran defensive back, who was benched in Super Bowl LII after a game-clinching pick in Super Bowl XLIX, expressed surprise that he's landed.
After taking part in the first day of the team's voluntary offseason program, Butler said he didn't expect to come back to New England.
One thing I learned is that you never burn your bridges down. As a grown-up, you handle situations as a man. I don't think I would have an opportunity to come back if I didn't do that.
After one year of retirement, he signed a two-year contract with the Arizona Cardinals on March 23 that could be worth up to $9 million. The catalyst for his return was the coach.
It really did come as a surprise. My agent told me that Bill wanted to talk to me. I was happy. I started working out immediately because I knew I could come back.
When the two talked, the other asked if he was locked in after a year off, and that they had already addressed his Super Bowl benching after that game.
He is confident that he will return to his previous form quickly.
I am confident that I got it. I have worked hard. I didn't sit on the couch all winter. I will defeat those odds.
He said that Belichick would always say "do what's best for the team" and at that time he thought he did what was best for him and his family. You cannot do nothing physically if you are not prepared mentally. I think I made the right decision.
I came out of retirement because I love football. I am grateful to have another chance to play.
