Karl Pryce has played for two of the four clubs to win Super League.
He started his career at Bradford Bulls who after four Super League titles, five consecutive Grand Final appearances from 2001-05 and a World Club Challenge win in 2006 are no longer in Super League.
He then joined Wigan Warriors on the eve of their 2010 Grand Final success.
So, the former Harlequins winger is best placed to shed light on why the top teams, aside from Bradford, have been able to stay at the top.
Since Bradford last won the Grand Final in 2005, only three clubs have won the Grand Fina with Leeds Rhinos winning seven, St Helens winning six and Wigan winning the other four.
Speaking exclusively to Serious About Rugby League, Pryce explained why these three teams stay at the top:
“It comes down to culture. When you’re at a top end club, Wigan, Leeds, Saints it’s all about culture, they all have top end cultures.
“At Wigan the culture ran right from the top to the bottom. It was about being as professional at possible at training and everything you do and I’m guessing it is very similar there and I know Leeds is very similar.
“It starts from scholarship all the way to first team which is why they always stay around the top three or four clubs.
“For me it’s all about culture. You start with culture. You need talent, you need the best of both.
“A strong culture will set you on the right path. If you’re a six out of 10 performer, but you change the culture of the club they become a 7 or an 8 out of 10.
“If you have a good culture, you have successful team and will win more games than you lose.”
