It wouldn't be easy for Burbo to have the Trbojevic name with Jake & Tom for brothers. He's obviously, and admitted to, bulking up in the off-season with the hope of establishing himself permanently in 1st grade. He's taken a leaf out of Jake's book and certainly isn't short on effort and is giving it his best shot to make it himself.
Interesting he's only been extended for 1 year, but I say good luck to him.
Possibly Ben’s choice and is backing himself to get a better contract at the end of 2024.
