After going undrafted in 2017, he emerged as a strong contender for the 2018 draft after an exceptional year, where he was named the Most Valuable Player (MVP) for both the GWS Academy side and the Allies team in the 2018 AFL Under 18 championships. That same year, he was named as the ruckman in the championship's All-Australian team.[2][1] He was then drafted by GWS in the 2018 AFL draft, when they matched the bid made by West Coast with the 34th selection.[3]
AFL career
Briggs did not debut for the Giants until late into the 2021 AFL season.[4] He only played 9 games in two and a half seasons, before being recalled in round 10 of the 2023 AFL season. He held his position for the remainder of the year and was considered one of the best ruckmen in the league.[5] In September 2023, after playing his first ever finals game, Briggs signed a two-year contract extension.[6]
