Personally, I was a critic of this trade and have seen nothing to change the mind.
Polak is yet to become the supposed primary Key Defender that he was recruited for.
Admittedly, Plough did say give him 12 months, so Polak can no longer play the Jason Cloke role in the back line for 2008, he must take the #1 forward.
IMO a big pre-season increasing strength, weight and pace is required to display that this trade was worthwhile.
