Although he may be worth it, I hope we don't pay over the odds for a back, simply because we declared our intentions to pick one up...
Is this really the player that we expect will help us with our deficiency?
We are not going to magically pluck a gun tall defender from another club without paying a heavy price. So a second-rounder for a good prospect developed by a successful club seems okay to me...
Laidler is a promising and versatile defender who can either go third man up or provide a bit of rebound. Add him to Jamison, Bower, Austin and White and hopefully we've got most situations covered, especially if Bower and Jamo can have improved seasons. He could also have the effect of releasing Gibbs or Lucas further up the ground.
I rate Laidler and whilst you're right that he might not necessarily be the ultimate solution to our problems down back, his addition would provide some good flexibility to our defensive structures.
