The deal is worth $20 million with $10 million guaranteed, including a $5 million signing bonus, a source told ESPN’s Dan Graziano.
The Eagles made a push to retain him but couldn’t close the deal, a source said.
The Eagles signed Robinson, 30, to a one-year, $775,000 contract late last March to add to what was considered a very thin cornerback group at the time. He was projected to start on the outside, but he struggled during training camp, heightening concerns that the Eagles were too shaky at corner to seriously contend.
Robinson was moved inside following the trade for Ronald Darby, and things began to click. He developed into one of the top slot corners in the game, pacing the Eagles with four interceptions and 22 passes defensed.
While he was key to the Eagles’ 2017 Super Bowl run, the Eagles, who are tight against the salary cap, were essentially priced out of the market for Robinson. They also are pretty stocked at cornerback, especially with Sidney Jones recovered from an Achilles rupture.
Prior to joining the Eagles, Robinson played one season each for the Indianapolis Colts, where he was limited to seven games in 2016 due to an assortment of injuries, and the San Diego Chargers.
Robinson spent his first five NFL seasons with the Saints, who made him a first-round draft pick after their Super Bowl win in 2010. But both sides were ready for a change of scenery after he experienced a number of highs and lows during his five years with New Orleans.
His best season with the Saints came as their No. 3 cornerback in 2011 before he struggled as a full-time starter in 2012 and had his 2013 season wiped out by a major knee injury. But the team showed persistent faith in him before he left as a free agent in 2015 — and they clearly still have that faith after watching him thrive elsewhere.
The Saints’ secondary drastically improved last year because of cornerback Marshon Lattimore, the NFL Defensive Rookie of the Year, and second-year cornerback Ken Crawley both having breakout seasons. But a nickel corner was a top priority for them this offseason.
Robinson has 14 interceptions and 77 passes defensed in eight NFL seasons.
