Is this the secret behind Tom Mitchell's Brownlow run?

Brownlow Medal winner Tom Mitchell has opened up on how a radical change in his life, prompted by his partner, may have helped take his form to another level.

The Hawthorn star revealed soon after winning the AFL’s greatest individual honour that his partner, Hannah Davis, had overhauled his diet, especially his pre-game meals.

“In the big picture my diet has improved a fair bit, so Hannah can take a lot of credit for that,” Mitchell told Sunrise.

Firstly the 26-year-old was a big fan of Uber Eats.

“I used to eat a lot of Uber Eats,” he said.

“I remember some weekends I’d get breakfast, lunch and dinner so I spent about $80 a day on Uber Eats … much better diet now.”

That may not sound like too much of a surprise, but what the former Swan was eating before games may shock you.

“I don’t know how much I want to say and go into too much detail,” Mitchell said.

“But in summary my diet wasn’t too flash before I met Hannah.

“My pre-game routine consisted of a box of Barbecue Shapes, a Kit-Kat and some Starbursts every night. Now I am on a strict salmon diet. So it’s changed a little bit.”

And so has Mitchell’s form.

Last year, Mitchell was runner up for the Brownlow.

This year, he blew his rivals off the park, averaging a league-high 35.7 disposals and 7.9 clearances per game during the home-and-away season and ranking third for contested possessions.

The gun onballer polled maximum votes in the first three rounds of the season on the way to a total of 28, claiming an unassailable lead after 21 rounds and outpolling Sidebottom (24) and Melbourne young gun Angus Brayshaw (21).

An incredible result for the Hawthorn star, and enough of an achievement to regress back into some bad ways.

“I’d be lying if I said I didn’t have a box of Shapes last night so I might have drifted back into my old habits,” Mitchell said.
