The former Cardinal agreed to a three-year deal worth a maximum of $33 million.
What it means: The Cowboys made their first splash free agent agreement since adding cornerback Brandon Carr on a five-year, $50 million deal in 2012. Thompson fills a major need in the secondary for the Cowboys. He has been a full-time starter the last five seasons with Arizona with nine career interceptions. He can fill multiple roles for new coordinator Christian Parker and has familiarity on the coaching staff with new corners coach Ryan Smith. The Cowboys need a communicator in the secondary, and Thompson can make sure everybody is on the same page. He is young -- turning 28 in July -- but has the experience to help a secondary grow.
