Rolle thanked the Bears on Instagram, writing:
Rolle joins the Bears from the New York Giants. He signed a five-year, $37.1 million contract with the Giants before the 2010 season and played every game of it, including the four games in the Giants' run to the Super Bowl XLVI title after the 2011 season. He also spent the past two years as a team captain and earned a reputation among players and coaches alike as a strong leader and team player.
"I don't think I've ever been involved with a player who was more sincerely interested in how his team could improve," Giants coach Tom Coughlin said of Rolle at the scouting combine in February. "And I admire that very much in him as a young man and as a leader."
Rolle, 32, recorded 464 tackles and 14 interceptions in his five seasons with the Giants and has a total of 799 tackles and 26 interceptions in his 10-year NFL career. He was a first-round pick (No. 8 overall) by the Arizona Cardinals in the 2005 draft out of the University of Miami, and he spent the first five years of his NFL career with the Cardinals.
Rolle was selected to the Pro Bowl after the 2009, 2010 and 2013 seasons.
