AFL Round-Up: Melbourne are more terrifying than ever and the key forward is king again in round five

There may still be a game to come, but round five has already been loaded with enough drama and talking points to get us through a Monday review.

Welcome to the AFL Round-Up, where we digest the week that was.

Melbourne will lose a game at some point this year. They'll get tired or hurt or bored at some point and get caught by an opponent at the top of their game on the day.

But watching that third quarter at the MCG on Saturday night, that concept was just about unfathomable. As the rest of the league settles into position for the campaign ahead, it's as clear now as it ever has been that the Demons are a level or two clear of the competition.

And they know it too.

That confidence doesn't manifest in arrogance or complacency but in a willingness to try things, to experiment and show off just to see what they as a collective are capable of.

The Demons exist in a sort of predictable spontaneity. We've seen enough of them now to know what to expect in any given game situation.

Quick clearance from the forward line? Steven May will lock down a forward, Jake Lever will try to float in and intercept, Jake Bowey will be waiting at their feet and Ed Langdon only a handball away on the wing to send it forward again.

Centre bouncedown? Max Gawn or Luke Jackson will get first hand on it, Jack Viney will block off any attacking lane for opposition midfielders while Christian Petracca and Clayton Oliver look to take it out the front by any means neccessary.

Rebound from defensive 50? Angus Brayshaw will start the chain floating back from the defensive wing, Charlie Spargo will run and carry, Bayley Fritsch and Sam Weideman will split their leads and Kysaiah Pickett will lurk and linger.

But inside that highly-predictable, highly-repeatable
