Silly question Scooper, but I'll give you an honest answer.
Dimma tried him as a defensive forward - maybe one reason for that was a back six that didn't require him given the form of Batch/Grimes/Houli. It also suited the lock-it in the forward fifty strategy Dimma was keen to use at certain times. You'd have to ask the selection panel but that's my reading of it.
We all know how that experiment turned out - one good game and plenty of bad. So back to the VFL he went. Now Grimes is out, Morris is in to do a job. We all know he's got serious limitations. But it's an honest assessment - his pressure and intensity is good one-out, given it's not a mismatch. Not perfect, but it's a strength he has.
You might disagree, that's fine. But the argument that because Dimma tried him forward therefore he can't defend one-out doesn't add up.
Oh, by the way, when Grimes or someone better is available, back the VFL he should go. But lets not make him out to be worse than he actually is.
