Walker would be great utility value. Can play lock, hooker, five eight, centre, probably second row at a pinch. Has a touch of class too having been previously a half / five eight. In fact, he's a beeter player than the Bulldogs utility signings, and those have worked our pretty well for them.
I would pass on Horsburgh. All he has going for him is "angry". Can you imagine the penalty count between him and Seyfarth and even worse if Bateman returns. Nathan Brown would have been a much better angry option, but we passed on the opportuntiy to sign him last offseason. Of the players that have apparently been given permission to look elsewhere, the only one I would think about is Shaun Lane. And only then on a 2 year deal. At least he would be another big, mobile body on the edge to complement Fainu, and he has an offload in him as well. Not bad targets for Luai and Galvin to be able to hit close to the line.
