I can halfway cop Gosiewski, we need an edge defender if nothing else. Piakura was found wanting there last year.
Shibasaki is going to have to win over a few fans, he's been given plenty of opportunities throughout his career. I don't know how serious the Bulldogs will be taking it but they torched our edges last year in the regular season so there will be a bit of pressure on.
Shibasaki must have had one hell of a pre-season because he's played 30 games for 4 different clubs across 6-7 seasons (there was a Rugby Union stint in there too). It doesn't exactly fill the average fan with great hope.
