Replacements?
Thaiday: wouldn't get too many more years out of him. Only got one year out of Cozza, but I don't think they'll go back. Sam seems happy enough with the senior statesman / funny guy role.
Glenn: possibly. He certainly gives the Broncos everything he has
Macca: maybe. He's definitely one of the key players, is spoken about well by other players, and dipped his toe into the leadership role the other year
Hunt / MILF: Milf too young. Hunt has enough on his plate. I think Hunt would be the obvious future choice?
Boyd: has come out of his shell since moving back to Brisbane and getting a few monkeys off his back. Has aimed up, set goals (like being a rep fullback), and achieved them. Absolutely passionate about his football at the moment, and gets a lot of credit for being one of the most professional footballers when it comes to training and preparation. Is old enough to lead, young enough to be there for a few more years.
Who know what Wayne thinks about anything? I wouldn't be surprised to see Boyd take the job on next year, though.
