DUSTIN Martin is the definition of a rough diamond, so it's only fitting that the superstar is taking Richmond's mature-aged draftee Marlion Pickett under his wing.

The Brownlow medallist has opened his home to Pickett, who the Tigers snapped up in this week's NAB AFL Mid-Season Rookie Draft.

FULL FIXTURE Every round, every game

Highly rated at WAFL side South Fremantle for a number of years, a history of off-field issues - including time spent in jail - had contributed to the 27-year-old Pickett being overlooked for higher honours despite plenty of interest.

But the Tigers believe his issues are in the past, and still chose to select the father of four after he had surgery to repair a broken finger.

Pickett will spend about a week living with Martin, who himself had off-field troubles before changing his ways in recent years.

For Richmond coach Damien Hardwick, it's all part of the club's rich tapestry.

The Tigers have reaped the rewards of recruiting Sydney Stack, another talented indigenous WAFL player who was overlooked by other clubs because of perceived character issues.

"The thing I love about our club is we sort of embrace those challenges," Hardwick said.

"It adds to the person's story and adds to our club's story along the way. The one thing I will say about footy clubs is they are fantastic at wrapping their arms around and giving people a chance.

"That's the great thing about sport in general - it allows people to grow and thrive and get better as a result."

Pickett's finger injury will sideline him for up to 10 weeks.

But judging by Hardwick's excitement at his highlights reel, he won't have to wait too long before he gets his opportunity.

"Have you seen his tape? I would have picked him this week, I reckon, if he didn't break his finger," a grinning Hardwick said.

"I think he's capable, there's no doubt. Learning the system will take some time, absolutely, but the reality is good players are good players."
