The Dolphins had three first-round draft picks in 2020. One of them, Tua Tagovailoa, had his fifth-year option picked up. The other two will not. The Dolphins are not expected to exercise the fifth-year option on either offensive lineman Austin Jackson or cornerback Noah Igbinoghene, according to Tom Pelissero of NFL Network. That’s no surprise, as both Jackson and Igbinoghene have struggled to live up to expectations as first-round picks. The Dolphins say they expect Jackson to start at right tackle this season, but last year he played in just two games because of two different ankle injuries. Igbinoghene has been an even bigger disappointment than Jackson, starting just five games through three NFL seasons. Both Jackson and Igbinoghene are slated to become free agents in March of 2024.
