"He's a proven coach, he's a premiership coach, he would certainly appeal to the supporters because he's a premiership coach.
"But also, to all the Lions faithful out there, he's a legend of the Lions, he's got that experience in taking a side to the next level, and when I say next level, that's to a top-four level which you need to play in premierships."
After the club sacked Michael Voss this week, Brown said he'd be shocked if the club hadn't had at least some "positive indications" from a potential new coach.
"I don't think a coach has agreed, but you would hope that there's some real positive indications," Brown said.
"I'm pretty confident that the club wouldn't be going into this cold.
"I'm sure that they've got some candidates in line that they've had some positive indications from."
Brown said he had found out some time ago the club was targeting Roos.
"I was aware, Vossy had told me that, he'd indicated that certainly Paul Roos would be spoken to, but that was told to me five or six weeks ago," he said.
"I don't think the whole playing group was told that, but certainly as the captain I was told that, so I understood it and Vossy was comfortable with the process."
Brown also said he hadn't made his mind up on his own retirement plans, but said with a new coach coming into the club, the decision might not lie solely with himself.
"I've still got to decide whether I want to go around again and play another AFL season," Brown said.
"I'm very excited about the future of the club, but I need to come to that decision also myself, but that might be taken out of my hands anyway, we'll wait and see."
