Revis was 27 years old when he was traded by the Jets to the Buccaneers prior to the 2013 NFL Draft. The Jets received the 13th overall pick in 2013 that they used on defensive tackle Sheldon Richardson, and a 4th-round pick in 2014 that they used on wide receiver Jalen Saunders. The Buccaneers signed Revis to a six-year, $96 million contract that tied for the highest-paid defensive player in the NFL at that time. The trade stemmed from Revis and the Jets' inability to agree to a long-term deal prior to the trade, as well as Revis' ACL injury that resulted in him missing 14 games in 2012. Revis was released by the Buccaneers in 2014 and retired earlier this year after being released by the Kansas City Chiefs.

The Falcons traded the 15th overall pick for Abraham and the Broncos' 3rd-round pick in 2006 and 4th-round pick in 2007. The Jets received the 29th overall pick from the Broncos that they used on center Nick Mangold.
