I was a huge Steve Scott fan in the 1980's, and I know all of his strengths and weaknesses physically and mentally as a 1500 meter runner. Here is my take.
Steve Scott was a strength runner but he also had a good kick. He made his living staying just off the pace and driving the last part of the race. In 1983, he finished second in the 1500 meters at the World Championships in Helsinki. He was outkicked by Steve Cram in that race because Cram was smart enough to stay just off the lead in a very slow paced race. Steve Scott got into some jostling in the middle of the race and finally made his way up just behind Cram in 3rd place. Scott had to use his energy to make this move before the bell lap. The pace at the 1000 meter mark was so slow that it was almost a joke. Scott made the mistake of being too far behind the lead at that point. Cram made the first bold move with one lap to go and that won him the race. Scott actually had a pretty good kick that day but he waited too long and Cram got the jump on him. This race unfairly branded Steve Scott as someone who couldn't kick. I disagreed with that sentiment. Maybe he couldn't kick as fast as Cram or Coe in a race that goes out in 2:06 for 800 meters. But Scott was a 3:47 miler who was a good kicker in a decent paced race.
Fast forward one year later just before the 1984 Olympic Games. All the track and field media were building this 1500 meter final into a battle of kickers: Coe, Ovett, and Cram. I have an article that I saved from 1984 that basically said that "Steve Scott can't kick with Coe, Ovett, and Cram. And the only chance Scott had to win was if the race was fast". I agreed with that point and I knew that Steve Scott needed to be patient and make his move between 500-600 meters to go if the race was very slow. He built his entire career as someone who stayed just off the lead and then used his strength to beat people in the end.
The strategy that Scott used in the 1500 meter final was doomed from the start. I think Scott went into a panic mode too early. He employed a stragedy that was foreign to him. I remember sitting there in the Coliseum and saying to myself "Oh nooo". I think he should have stayed patient and try to work the last 600 meters. IMO he would have finished 3rd with that tactic. He was never going to medal by pushing the pace with 1100 meters to go in the race. I think he had a better kick than he gave himself credit for. I believe he read the newspaper reports about Coe, Ovett, and Cram. I believed he went into a panic mode with 1100 meters to go. Steve Scott did not run smart on that day. But he still has my respect as a great American miler.
