I imagine we'll find that out during the preseason, because all three are possibilities.
If it had been Giles, reserves was the only possibility.
I disagree, but it's clearly not worth discussing any further than we already have.
We have to back Walsh in now to get the most out of what he's got, but I hope that Walker/Jenkins/Lowden get first crack at it, with the threat of Pods to keep them honest should any of them prove inadequate in whatever role they're given.
