Chinese basketball icon Yao Ming has been taken aback by Jeremy Lin's rise at the New York Knicks and thinks his style and size could make the state sports system rethink how it selects and grooms its athletes.

Yao, who opened up the world's most populous country to the NBA, retired from the game last year. In 2002, the 2.30m former Houston Rockets center was the first international player to be top pick in the NBA draft and was an eight-time All Star.

Chinese-American Lin has taken the NBA by storm with a series of dynamic displays at point guard for the Knicks. His fast-paced, high-scoring, playmaking performances could hardly be more different from the towering Yao's plodding, robust style.

Shanghai-native Yao said Lin, who stands 1.91m, could change the way China selects and trains its basketball players.

"This is something else that Jeremy Lin has brought to us. It has given us something to reflect on, whether there are imperfections over the development and selection process for our basketball players over the past 10 or 20 years," he said.

The soft-spoken 23-year-old Lin from Harvard went undrafted and was cut by Golden State and Houston before finding a place at the end of the Knicks bench in December.

Given his chance, Lin seized the NBA spotlight with both hands, and has inspired the Knicks with a string of stunning performances.

Yao said he had known Lin was a good player but was stunned that he was able to reproduce the sensational form night after night.

"I am very surprised but also very happy. When he played well in his first game I thought this was a great start and perhaps he would soon have more stable game time. But I never thought he would perform up to such levels as he had today."

Role model

Lin has said he communicates often with Yao, who he regards as a role model. Yao said he did not have much advice to give because of their different backgrounds but had always encouraged and cheered him on.

"First, New York and Houston are different. Also, the cultures of the two basketball teams are different, the cities are different, the teammates he faces are different, so I don't wish to tell him too much.

"If I do so, perhaps I will give him too much pressure."

Since retiring last year due to a succession of foot and ankle injuries, Yao has embarked on a new journey in life.

With numerous projects on hand, Yao feels like life has become more of a marathon than a sprint.

"Perhaps in the past it felt like I was doing the 100m sprint, but now I feel I am more of a long distance runner," he said.

"For the 100m, you need to just spend a short time doing the sprint, and for the rest of time you can choose to walk, jog or even lay on the ground and not move.

"For now, my working hours are getting stretched everyday, but in terms of individual units, you don't have to be moving as fast as sprinting."

The Chinese national basketball team is adjusting to life without the retired Yao. China regained the Asian Championship title in Wuhan last September and qualified for London, and Yao said the team should grasp its opportunity to shine at the 2012 Games.

"Being in the Olympics is a once-in-a-lifetime opportunity. No many people can have the chance to participate in the Olympics three or four times," he added.

"So once you are in the Olympics, you have to try your best and try to fulfil the team's biggest potential to get the best results," he said.
