I'm not entirely sure on the specifics but after Bunn left the word was that Brendan Barlow and James Hinchy would step into replace them. Initially it appeared that Bunn was going to pursue a real estate career but then he went ahead and signed with Melbourne in 2012. Both Barlow and Hinchy were let go at the end of the 2013 season which tells you just how well they went and the Broncos brought in Peter Nolan.
Nolan has had a mixed bag since returning to the Broncos. You would have to say the signings like Darius Boyd, Adam Blair, James Roberts had more to do with Bennett and even guys like Ese'ese were picked up from an affiliate instead of being specifically head hunted. That leaves Pangai Junior, Haas, Moga and Mead as his notable NRL calibre signings.
Then again it's always difficult to judge an recruitment officer when a big part of their job description is bringing through juniors. In the case of Barlow, while most would regard his stint as a failure, he was the one who discovered Tino Faasuamaleuai as a 12 year old in Gympie. So every recruitment officer has their share of stories.
