I was never gutted about losing Galvin as I always felt he was overhyped. I also think we cover Luai easy so I am not fussed....
However, I would be really concerned with losing Bula. While he is not the developed package, he is so critical to our attack. He is by far our biggest threat and if you don't have a huge threat at #1 I don't think you go anywhere. With respect to people suggesting Turuva as the replacement fullback, please go watch last years games at #1, he was a stop gap (defensively good, no threat in attack) at best. Maybe Attard may be okay, but I am far from confident, as I heard many of the same people talk up guys like Heath Mason who is not even close.
To people suggesting our squad is far better than the Bulldogs, well swap Bula into their side and that is certainly not the case. He would take them to another level. Tracey is a safe fullback, but is the least threatening attacking fullback in the competition.
