The price is fairly cheap for a cornerback-needy Steelers squad. Boykin will step in immediately and start in a secondary with many questions.
The starting slot corner is in the final year of his contract and will make $1.54 million this season. Boykin was the Eagles' best cornerback in 2014 and rated No. 21 overall by Pro Football Focus.
Much has been made the past two seasons about Boykin's desire for a bigger role outside of slot coverage. The 25-year-old would likely have left in free agency after the season.
Boykin spent three seasons with the Eagles, starting in six games. He compiled seven interceptions, including six in 2013, and forced four fumbles in that time.
