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 badly 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. He spent his first five NFL seasons with the Saints. He has 14 interceptions and 77 passes defensed in eight NFL seasons.
