Boldin took the high road and wasn't critical of the team in a statement emailed to The Baltimore Sun.
"I thank the Ravens fans for their incredible support for myself and my family throughout my years in Baltimore," Boldin said. "I am grateful in getting to know you and will miss what I call home. I thought this was the last stop of my career, but regardless of the circumstances, I came here to win a championship, and in February we came home champions."
Boldin was a central figure in the Ravens defeating the 49ers in the Super Bowl, catching six passes for 104 yards and a touchdown for a total of 22 receptions for 380 yards and four touchdowns in the postseason.
Boldin, 32, was traded after a contract dispute with the Ravens when they asked him to lower his base salary from $6 million to $4 million. The Ravens picked up $6 million in salary-cap space by trading Boldin.
