Philadelphia acquired Ronald Darby for Jordan Matthews and a…

Philadelphia made the deal because its cornerback room needed a proven starter, and Ronald Darby arrived with two years remaining on his rookie contract. The price was wide receiver Jordan Matthews and a 2018 third-round selection. Darby's first Eagles season was interrupted by an ankle injury in Week 1, but he returned in November, started seven regular-season games, intercepted three passes and then started all three playoff games during Philadelphia's run to the Super Bowl LII championship.

That postseason role matters heavily in hindsight. Darby was not a one-game rental; he played three seasons for Philadelphia, and his strongest value came when the Eagles were trying to solve a clear weakness on a championship-caliber roster. Even with injuries limiting his availability, the trade gave Philadelphia a starting outside corner during the most important stretch in franchise history.

Buffalo's return was not empty. Matthews caught 25 passes for 282 yards in an injury-shortened 2017 season before leaving after one year. The more durable piece was the third-round pick, No. 96 overall, which became defensive tackle Harrison Phillips. Phillips played four seasons for Buffalo, appearing in 45 regular-season games and starting eight in 2021 before signing with Minnesota. He gave the Bills useful interior depth and eventually starting snaps.

The original Buffalo-favored verdict undervalues Darby's championship contribution. Phillips was a sound third-round outcome, but he never became a cornerstone for the Bills, and Matthews did not provide lasting receiving value. Philadelphia, meanwhile, turned the package into a starter who was on the field throughout a title run.

The Eagles deserve an A because the acquisition directly strengthened a Super Bowl-winning defense and produced multiple seasons of service. Buffalo earns a B- for landing a useful defensive tackle plus one season of Matthews. The proper hindsight verdict is a Philadelphia Eagles win.
