The respected former Western Bulldogs star is regarded as one of the most successful ruck-forwards of the modern era.
Mobile and skilful for a big man, Darcy won the Bulldogs best and fairest – the Charles Sutton medal – in 2001, and was also awarded the venerated Leigh Matthews Trophy as the AFL Players Association Most Valuable Player in 2002. He would also win the club's goal-kicking title in 2004, before repeated serious knee injuries brought his career to a close at the end of the 2007 season.
A member of the AFL Rules Committee and a father-of-four, Darcy has carved out a burgeoning career as a radio and TV personality since he hung up the boots.
Luke says he’s genuinely excited about being part of the Seven commentary team and the people that make the coverage.
"I’m looking forward to working with icons and legends of the game in the Seven line-up. It’s going to be a fun year."
His calling style will be unfiltered as always. "I'll call it the way I see it, there won’t be any hesitation in going for it if I feel it's warranted. That's the only way you can do it to be true to yourself.
"But overriding all of that I want to have fun. That's what footy is all about and this is the best job in the world."
In 2012 Luke says there's going to be a lot of intrigue in the first year coaches; Brenton Sanderson, Mark Neeld, Scott Watters and Brendan McCartney along with the coaches in their first year at a club, Ross Lyon and Kevin Sheedy.
"There will be a lot of interest in how they perform and what fresh ideas they bring to the table.
Luke also believes last year was one of the best years for high marks which he loved. "It's a unique and best part of our game. And I look forward to more long kicking and more high marks."
When the talk turns to premiership hopes, he says he really likes the Hawks' chances this year.
"Last year they had big injury issues in defence and yet they still managed to cover that well. If they’re anywhere near full strength they'll be up there in contention.
"But I'll pick Collingwood to win it. Injury and suspension hurt at end of last season and they’ll be very hungry for success this year and Buckley will deliver a fresh approach."
Luke can also be heard on Triple M’s Hot Breakfast program during the week.
