The Jacksonville Sharks named James Fuller as their new coach, after the National Arena League team and Coach of the Year Siaha Burley could not agree on terms for a new contract.

Just a month after winning their second National Arena League title, the Jacksonville Sharks are introducing a new coach.

Former Sharks defensive coordinator James Fuller will take over as the NAL champions' head coach, the team announced Wednesday.

He replaces Siaha Burley, who won the league title in 2017 and 2019. The club said that it was unable to agree to terms on a contract extension with Burley, the NAL's coach of the year.

Burley took over the Sharks midway through the inaugural NAL season in 2017.

"Coach Burley’s success here in Jacksonville is a great indication of his talents," Sharks chairman Kevin Wezniak said in a statement. "He built a great roster this year, chose an outstanding coaching staff, and will be a winner anywhere he goes."

Fuller, 50, played as a defensive back at Portland State and spent portions of three seasons in the NFL from 1992 through 1996 with the San Diego Chargers and Philadelphia Eagles.

He has prior NAL head coaching experience, leading the Maine Mammoths in 2018, and earned recognition as the league's top assistant coach this year after commanding a Sharks defense that led the six-team lead in most turnover-related categories in 2019. In addition, he twice served as interim head coach in the Arena Football League and led the Professional Indoor Football League's Richmond Raiders for four seasons.
