The Jacksonville Sharks moved from the AFL to create their own league in 2017, forming the National Arena League. Unsurprisingly, the team blew through the 2017 season, going 11-1 in the regular season and taking the league title two games later. All regular season victories in 2017 came by at least 14 points, until a final game loss to Monterrey. AFL quarterback Tommy Grady played five games for the team, passing for 1,060 yards and 23 touchdowns. Damien Fleming took over for the rest of the year, throwing for 18 touchdowns and 1,047 yards, highlighting the potential AFL-NAL talent gap. The Sharks found another arena league vet to play quarterback in 2018, with Adrian McPherson throwing for just shy of 2,000 yards and 34 touchdowns. The rest of the league caught up in 2018, as Jacksonville lost three of its first four games and went 10-6. Carolina blew out the Sharks 73-48 in the playoffs and went on to win the 2018 championship. The Sharks cruised to a 13-1 regular season in 2019 and won the NAL title on a TD pass with 10 seconds left. The 2021 squad went 3-5 and missed the playoffs. The Sharks returned in 2022 and went 7-7, qualifying for the final playoff berth. Arvell Nelson quarterbacked the team, passing for 2,005 yards, 40 touchdowns and eleven interceptions. Nyqwan Murray led all receivers with 723 yards and nineteen touchdowns. On defense, Anthony Johnson and Miles Kelly both sacked opposing quarterbacks six times. The Sharks got out to a 1-4 start, losing three games by seven, one, and five points. Jacksonville traveled to Albany in the semifinal round and fell 68-67, despite scoring 43 second half points. The team returned in 2023 and went 10-3 in the regular season, clinching the top seed for the playfofs. After a 62-18 drubbing of Jacksonville, the Sharks hosted the national championship game. Jacksonville trailed Carolina 31-14 in the first half, but rallied for a 54-45 title victory. The team left the NAL in 2024 for the newly reformed AFL.
