Bradman Best's younger brother Baxter has signed with Newcastle for 2027, giving the centre another reason to consider staying with the Knights.
"My brother did just sign with Newy. So there's definitely reasons to stay," Best said.
Best will give Newcastle the first chance to make its strongest offer before considering interest from rival NRL clubs.
His current Knights deal expires at the end of 2027, and he has been able to field offers from other clubs since November began.
"I love the coach (at Newcastle). I want to sit down and give the Knights, Justo (Justin Hollbrook) the first crack at it."
He said the pair would talk after the World Cup final, but added: "But at the same time, I'm a father now. I've got a little daughter, and I've got to do what's best for me and my family."
The 25-year-old had an impressive 2026 season with Newcastle, which came close to winning the premiership.
Best's representative profile includes two tries on his State of Origin debut in 2023, a crucial score in the 2024 Brisbane decider and a long-range try in the 2026 Suncorp decider.
"I'm just gonna worry about that after (the World Cup final)."
