Stand by for more interchange madness. That is the strong message to come from this year's NAB Cup.
On the eve of the AFL premiership season, clubs are bracing themselves for another explosion in the number of interchange rotations.
The figure, which has climbed dramatically in recent seasons - from 30 per side in 2004 to 80 last year - is set to reach a new level again as clubs tell their players to go hard and then get off.
This year's NAB Cup revealed some eye-popping numbers.
While a lot of the pre-season talk has been about zoning, interchange numbers went through the roof.
Collingwood made the most ever moves in a game in round one against West Coast, recording a remarkable 137 on spacious Subiaco Oval.
This smashed the previous record of 119 by Melbourne last year.
Amazingly, the Magpies made a change every 47 seconds during the 107-minute match.
Fremantle then broke Melbourne's old record, making
121 interchanges against Richmond.
Rotations rose to such an extent that six of the top eight highest interchange moves in a game were recorded during the NAB Cup.
Collingwood - whose coach Mick Malthouse has taken the mantle as king of rotations - followed its record 137 with 114 against Richmond and 118 against Essendon.
Hawthorn and St Kilda also set club records, recording 114 interchange rotations against Melbourne and Brisbane.
Overall, the number of rotations per side in the four-week series was 104.4 - 24 more than last year's record home-and-away season average.
While NAB Cup games have a history of throwing up exaggerated statistics, Port Adelaide assistant coach Matthew Primus says the numbers are a clear warning sign bench moves are going to explode to a new level.
"They'll rise again, there's no doubt about that," he said, adding the use of the interchange bench is one of the biggest changes the game has seen.
"That's the way the game's going."
Teams were always going to make more rotations during the NAB Cup because they have more players on the bench (six players instead of four plus two 'substitutes').
But countering this effect is that games were, on average, 15 minutes shorter than they are in the season proper.
Last year the AFL capped
interchanges in the NAB Cup to 16 per quarter.
This year there was no such ceiling and clubs took full advantage.
"Whichever way you look at the numbers, I've got no doubt what we've seen indicates there will be more interchange moves this year," Primus said.
"It's been a talking point among the coaches."
The Power averaged 95 moves in matches against Sydney and Geelong, ranking 12th in the league.
Hometown rival Adelaide made 86 moves in its round-one defeat to eventual premiers Geelong.
In looking to gain a competitive edge, Primus said clubs had instructed their players to go as hard as they could for as long as they could and to take themselves off the ground when they are spent.
Once they regained their breath, they were sent back on.
Primus said apart from not fielding tired players, the other big advantage of making wholesale moves was to play havoc with the opposition's match-ups.
"It can create a bit of angst for coaches when the match-ups change so often," he said.
"Clubs definitely use the interchange bench to their advantage.
"If you're not using it, you lose out."
