Getting Patton for Watson would actually be a win for us.
Jamison is coming towards the end of his career. So I expect to see us try and get another tall defender type this year. Rowe and White are doing good as the second and third defenders respectively. We have McInnes as backup to White and we could, at this point in time, possibly use Giles as cover for Rowe (even though he really isnt ready yet...).
Patton would allow us to use Waite as cover for next year and allow Lachie and Casboult to continue their roaming ways. I think that getting Jaksch would require us to continue to play Waite as one of our 3 main forwards next year while we finish putting some polish on him.
