Hawthorn Coach Sam Mitchell says his side was "taught a lesson" by Sydney in Sunday's 76-point win at the MCG, but added he couldn't question the effort of his players like he had after the heavy loss to Gold Coast two weeks ago.

Despite winning or breaking even across many key statistics across the match, the Hawks leaked 18 goals to the Swans, including seven unanswered either side of the first break.

"It was a strange game," Mitchell said.

"I remember looking at the stats halfway through the third quarter, we were winning the inside 50s, we were well in front in contested possessions, winning the front half turnovers, and we were 70 points down."

Despite the final victory margin making it Hawthorn's biggest defeat of the season to date, Mitchell was encouraged by the effort of his players.

"The margin is worse than the Gold Coast game, but I looked at today's game, if you watched it without a scoreboard, you would have said the brown and gold boys are having a crack. They're really putting a lot of pressure on the opposition," Mitchell said.

Sydney's potency inside 50 was a continued concern for Mitchell throughout the day, causing some shifts in personnel as the game wore on.

Blake Hardwick, who started well up forward, was moved into defence and substitute Max Ramsden was injected into the game as a second key forward option, but nothing worked for the home side.

Losing tall forward Mitch Lewis to knee soreness before the bounce for what would have been his first game since Easter Monday also didn't help.

"It's never a great phone call when the physio rings you, it was probably around 10 o'clock or so this morning, saying 'I don't think Mitch is going to get up for today'," Mitchell said.

"I thought collectively our front half didn't function as well as we would like."

Lewis' availability for next Sunday's clash with the Western Bulldogs remains unclear, while Mitchell also made note of young Hawk Sam Butler's broken leg in the VFL earlier in the day.

"He broke his leg in pretty horrific circumstances, so all of our thoughts go out to him ... he's going to have some surgery tomorrow and he'll be out for the season," Mitchell said.
