Richmond star Dustin Martin is open to the highest bidder, according to SEN regular Greg Denham.

As Martin’s contract saga rolls into Round 20, Denham, who earlier this year was confident the star playmaker would remain at Tigerland and hinted a deal could be done prior to the season getting underway, believes the goalposts have changed.

“If someone offers so much money that it’s getting beyond ridiculous for Richmond to pay that money, then I think he might leave,” he told Hungry for Sport.

"I never thought he would leave Richmond, but it's now highest bidder."

It’s been rumoured North Melbourne’s offer is in the vicinity of $1.5 million per season and far superior to the six-year $1.2 million a season offer from Richmond.

The Australian journalist has suggested Hawthorn might be a new player in the market for the 26-year-old.

With Luke Hodge announcing his retirement, and Josh Gibson expected to do likewise, in addition to the 20 per cent increase in salary cap, the Hawks could have enough funds at their disposal to make a play for the Brownlow Medal favourite.

“I wouldn’t be surprised if Hawthorn has a massive interest in Dustin Martin,” Denham said.

“There was a massive rumour last week it was Sydney but they’ve absolutely denied it on all fronts because they don’t have the money.”

If Martin does depart Richmond – which is shaping as more likely than less likely with every passing week – he could become the first player to leave a club a season after winning the Brownlow Medal.

In the wake of Patrick Dangerfield’s suspension, the key midfielder is a raging favourite to win this year’s award.

No out of contract player has ever won a Brownlow Medal.
