Part 2/10:
Sullivan started his college career as a wide receiver but transitioned to tight end in his final season. The Seattle Seahawks drafted him in the seventh round as the 251st overall pick. Despite being on the practice squad and serving a minimal role in 2020, Sullivan's time at Seattle was tumultuous, including experiments at both tight end and defensive end. In 2021, he signed a Futures Contract with the Carolina Panthers but spent much of his tenure on the practice squad. In the 2022 season, Sullivan contributed by catching two passes for 46 yards.
