"But how it turns out I don't know."
The Knights have made a number of signings for next season.
Connor Watson, Tautau Moga and Kalyn Ponga headline the young backs coming to the club, while Aidan Guerra and Herman Ese'ese will arrive in the forwards.
But Blair would offer the winning culture and experience so desperately sought after at the Knights given he has played four NRL grand finals and won a World Cup in his 12-year career.
"All I can guarantee is he is a player of interest for us," Brown said.
"He is certainly someone we feel would help our young forwards, the (Daniel and Jacob) Safitis, (Josh) Kingy and Barny (Mitchell Barnett) with his experience.
"He's come from the Melbourne Storm and he is a winner and he knows how to prepare to win.
"He is certainly someone who would help our organisation move forward a lot."
