The promising ruckman was Adelaide’s first pick in the 2014 AFL Rookie Draft following a strong season with Calder Cannons in the TAC Cup, and two games for Coburg in the VFL. Standing at 201cm, O’Brien developed into one of the leading ruckman in his first SANFL season before he finally broke through for his AFL debut in Round 20, 2016, against Brisbane. While he remained an understudy to Sam Jacobs, O’Brien was elevated off the rookie list for the 2017 season and he continued to shine in the SANFL. In 2019, he got his opportunity at AFL level when Jacobs suffered a knee injury and the 23-year-old has made the spot his own.
