FWIW, the Champion Data guy agrees with BV. H just needs to ruck for 5 min a quarter. Let TDK do the rest of the work.
I'm not as convinced myself, so lets see what the selectors come up with.

Hoyne says the Blues should stick with that mix, saying Tom De Koning has had an excellent six weeks in the ruck.

“I just want to put this on the agenda for Carlton supporters as well,” he said.

“His best position, the last six weeks, he is clearly a ruckman. He is not a forward.

“I would not be playing Pittonet. I would be keeping this really simple. Let this guy go.

“As a ruckman over the last six weeks he’s been the eighth best ruckman in the competition. As a forward, sixth worst forward in the competition.

“Just put Harry McKay in the ruck for five minutes per quarter. The second ruck role, we talk about it a lot, it’s 20 minutes a game. Don’t lose sleep over it.”

This is an enormous swing in two months, with Hoyne saying mid-season that Pittonet statistically was a significantly better ruckman than De Koning. The young Blue has clearly broken out since re-signing.

Harry’s fourth quarter efforts are sometimes game saving for us. Wasn’t last week or the week before but he’s capable of dominating our transition game from goal square kick outs.

And yet Charlie takes as many marks outside 50 as Harry does.
He also leads the AFL for goals, is top 5 for contested marks, marks inside 50, score involvements, offensive 1 on 1 wins etc.
Adaptable, versatile.That's his value.
No one disputes Harry's potential but we have too many 1 dimensional talls. He's one of them. That's why Jack get's a game. He's not as tall or skilful as the rucks but he can adequately perform other roles. If Harry could also do it, he'd offer enormous value to us.
