Time will tell but history shows one preaseason isnt usually enough when you';ve had a long lay-off. After the way Dawson botched the Gf and with thr retirement of Hudghton I would have thought Maguire would have been a more than handy back-up.
Hell you drafted Pattison who at best if a fourth ruck option and arguably fifth or sixth - surely Maguire is more likely to be required as a back-up defender and potential first 22 player than Pattison is ever likely to be needed in the ruck.
Methinks the main reason StKilda burned Maguire is because they couldnt fit him in the salary cap and/or they needed to make cap room for Andrew Lovett.
No doubt the Saints coaching staff will be knocking on your door as a consultant, given you know the vagaries of their list far better than they do. I'm constantly amazed at your in-depth knowledge of the Saints internals. Clearly you have great sources in the Saints inner sanctum.
