GIANTS coach Leon Cameron has put the onus on his entire side to hit back hard from their shock round one defeat.

The premiership favourites were delivered a stern wake-up call as Adelaide cruised to a 56-point victory at Adelaide Oval on Sunday.

In sweltering 33-degree temperatures, the Crows booted 20 goals to 12 after quarter-time to stun the most fancied team in the competition.

Cameron said the GIANTS would have to learn their lessons quickly before they host Gold Coast at Spotless Stadium on Saturday.

"There will be some players disappointed in their performance, and I'm not just talking about our kids," Cameron said.

"I'm talking about our fifth, sixth year players that we expect more of when the whips are cracking.

"They have shown they can bounce back.

"I'm confident we can address some of the issues and have one huge crack at the Suns next Saturday."

Cameron didn't mince his words when asked what those issues were.

"Getting smashed everywhere on the park," Cameron said.

"We were a little bit lucky in the first quarter to be a couple of goals up, even though it was probably our best quarter, so that's saying something.

"But even then halfway through the second it was OK, but we just made some horrendous mistakes, and they pounced on them and hurt us on turnover.

"And their work at stoppages was far better than ours, which was really disappointing."

The GIANTS were soundly beaten in the midfield, a phrase hardly used last year.

They lost the contested possession count (147 to 130), made 10 less than tackles (60 to 50) than the Crows and had 66 less possessions.

"I thought we just gave it back to them too easy and then they really hurt us," Cameron said.

"When you're chasing and you're chasing even more, credit to them, they used the ball better than us and were hungrier than us around stoppages.

"In the end, that's the difference."

The GIANTS were down to 21 players for the majority of the game when Fremantle recruit Tendai Mzungu sustained a hamstring injury in the second quarter.

"It hurts your rotations a little bit, but at the end of the day you've got to deal with it and we didn't deal with it really well," Cameron said.

"But that's not the issue.

"The issue is in parts of the ground, stoppages, us burning the ball, the Crows hurting us on turnover, was the big area of concern."

GIANTS forward Jonathon Patton will be monitored after picking up a knock to his hip.

"He copped a really good corkie, so he struggled to run out the back half of the game," Cameron said.

"We'll see how he is in the next couple of days."

Mzungu will miss the game with the Suns, and could be sidelined longer depending on test results.

Cameron said Jacob Hopper, Sam Reid and Daniel Lloyd would be in contention to come into the side to face the Suns.
