The sixth team in this series are Leeds Rhinos, a side that has become well-known for its production of youth. The likes of Rob Burrow, Danny McGuire, Kevin Sinfield and Ryan Hall were all products of the Rhinos' academy and are just some that have made a name for themselves in the Super League as a Rhinos' youth player. Since the so-called "Golden Years" of the Leeds production line, others have come to the fore in recent years such as Liam Sutcliffe, Jimmy Keinhorst, Jordan Lilley and, most recently, Jack Walker. And, with an abundance of young players still ready to make their name, Leeds are in a great position for the future.

After a record-eighth Grand Final victory in 2017 in what was Danny McGuire and Rob Burrow's last ever games in a Rhinos' shirt following their highly successful careers at the club, head coach Brian McDermott will be looking for more of the same from his chargers. And, one youngster in particular has the talent to shine for the Rhinos as they look to defend their Super League crown in 2018.

Mikolaj Oledzki

Polish-born prop Mikolaj Oledzki has an upbringing like very few in Rugby League. As a youngster, he was a junior diving champion in his native country and was actually part of the Polish international diving team before making the move to West Yorkshire nine years ago from Gdansk. Whilst in West Yorkshire, Oledzki discovered Rugby League - starting with East Leeds and then Hunslet Warriors - before the Rhinos brought him into their scholarship programme in 2013.

Oledzki's performances for the Rhinos' academy have been so impressive that in 2016 he was called up to the England Academy squad's tour of Australia and was even handed a five-year deal by the Rhinos in July of that year, despite having only played the sport for four years.

At 6 ft 3 and 110kg, Oledzki is a towering figure, and, aged just 19, the Pole's future potential is quite scary.

In 2017, Oledzki made just three appearances for the Rhinos, but, in all three occasions - against Doncaster in the Challenge Cup and Catalans and Warrington in the Super League - he impressed with his hard-hitting defense and bullocking runs.

For the majority of the 2017 season, Oledzki was on-loan at Bradford Bulls where he played 20 times, standing out on the side in what was a disappointing season for the Bulls.

Known for his big minutes and large engine - which as a prop is no mean feat - as well as being surprisingly mobile for such a big player, Oledzki is definitely ready to make the step up for the Rhinos in 2018 and will definitely be one to watch in the future.
