Great summary and an excellent point re Howe
The conspiracy theorist in me thinks that the reason Darcy has been sent back is because they are committed to Mason Cox and so need to find him a role to justify said commitment.
Grundy has dibs on first ruck and Mason isn't mobile enough to play anywhere else but key forward so Darcy's been retrained as a back
the issue is Reid is cooked and cant play back anymore. therefore he has to go forward and given the 3 year deal with Cox (massive mistake) Moore has to go back.
I'll add I said almost a year ago Moore would be a superstar at CHB. that still stands.
