The retired Carlton and West Coast star told-all in his new book, Inside: The Autobiography.
Judd and Cousins shared the field at the Eagles from 2002-2007, with the former revealing the extent to which his teammate battled with his addiction.
The extract from Judd’s book was published by the Herald Sun.
“Addiction is all-consuming. I think Cuz began to feel he couldn’t trust many people at the club,” Judd wrote.
“The balancing act was like walking on eggshells. Cuz’s relationship with many people, including me, began to change… I was left with conflicting emotions… I recognise his enormous desire for success had been the driving force that led many of us… on the other hand, Cuz the drug addict was now posing a threat to the culmination of the football club’s mission, and my childhood dream.”
The two-time Brownlow medallist detailed how he believed Cousins’, “million (mile) an hour,” lifestyle lead to his crippling drug-addiction, and that these substances provided for him an escape.
This hectic state of mind translated into every aspect of Cousins’ life according to Judd.
Cousins’ obsession with his weight and diet is detailed by Judd in the autobiography.
He, “wouldn’t touch sugar in any form,” Judd revealed, as well as noting that he thought Cousins’ obsessive nature was the major driving force behind his personal success.
Judd retired from the AFL midway through 2015 after injuring his knee playing for the Blues against the Crows at the MCG.
He played 279 games, claiming two Brownlow Medals, five club best-and-fairest awards and a Premiership with the Eagles in 2006.
