Rugby league players cross over to rugby union all the time, at all levels of the game, and vice versa. Wherever the opportunity is, that's where the player will be.
With the NRL's State of Origin creeping up to our doorstep, and selection as always proving a topical issue, let's take a look at a few union players who could've gone down the other path and possibly been SOO representatives in Rugby League.
Kurtley Beale is one of the most talked about rugby players on the planet right now, as the ink still dries on his mega contract with Wasps. However, he could've easily been lining up for the NSW Blues next week.
Beale played his junior footy with the Western City Tigers rugby league team based in his hometown of Mount Druitt, New South Wales, before gaining a scholarship to prestigious private school St. Josephs College in Hunters Hill.
He was training with the Waratahs by the age of 15, signed his first contract at 16 and was training with Australia by 17, on the special invitation of then-coach John Connelly.
Tevita Kuridrani's selection for the Queensland Maroons would create a stink that has hung over the Queenslanders for a long time now, but nevertheless, he is eligible for them.
He played both codes as a young lad growing up in Corinda, and is related to greats from both codes, such as Nemani Nadolo, Noa Nadruku and Lote Tuqiri.
Ultimately, a top season with University of Queensland in 2009 saw him go down the path of union, and he has since played 57 times for the ACT Brumbies and 31 times for Australia.
Of anyone on this list, Wycliff Palu came closest to actually playing in the NRL, spending a short stint with the St George Illawarra Dragons in 2003 before returning to rugby union before the start of the NRL season.
Since his return to his native code, he has become a legendary figure within the NSW Waratahs and the Wallabies, registering 121 and 57 caps respectively. A fantastic record, considering how long he has spent on the sidelines.
With the talent and versatility the 6'4, 120 kilo back rower posses, it's very likely he would've suited up for the NSW Blues on more than one occasion.
Going from big to bigger, Will Skelton is arguably the biggest man in all of the sport of rugby right now, standing at a massive 6'8 and breaking the scales at 140 kilos.
Thus far, he has played 14 times for Australia, and he could've been wearing a different gold jersey if he had stayed in his native code rugby league, where he played for the Wentworthvillle Magpies, feeder team of the Parramatta Eels.
Would Skelton have enjoyed as much success at a young age in league that he is in union? Would his size have helped or hindered him? We'll never know, but it's sure fun to think about.
This is where it gets interesting. Not only is James O'Connor eligible for Australia, New Zealand and South Africa, he is also eligible for both New South Wales and Queensland.
O'Connor was born on the Gold Coast and went to boarding school at St. Josephs College in Nudgee, but not before spending a few of his teenage years playing in the Eels' junior system in Sydney, NSW.
The man himself said that at the end of the day, it was the Parramatta or the Western Force, and rest is history.
All Blacks rising star Nehe Milner-Skudder playing for the New South Wales Blues? Believe it or not, it could've happened.
Of course Milner-Skudder is eligible for New Zealand – he was born and raised in the Land of the Long White Cloud. But he also spent two years playing in the under-20s for the Canterbury-Bankstown Bulldogs in Sydney.
Under the same eligibility ruled that could've seen Sonny Bill Williams suiting up for the Blues, Milner-Skudder could've technically turned out for NSW, though it is likely he still would've chosen to represent his native land.
