“Any time someone shows some personality on the track, the first thing people say is: ‘the sport needs that, this is what the sport needs!’ We had the best showman ever in sport, for 10 years, Usain Bolt. Did this sport end up improving because of that? No. We’re still in the situation where the sport needs better marketing.
“We need to focus more on the competition between the athletes as opposed to finding another Usain Bolt and just putting all of the attention on him… [Bolt] didn’t bring more sponsors in the sport, didn’t create more media around the sport. When he left, all of the following for Usain Bolt went with Usain Bolt.”
