PV, Jav, and Hurdles can be great equalizers. You can take a lesser athlete (as defined by speed, strength, power) and get them to beat their better counterparts through these events. In the decathlon it’s amazing how little it takes to gain a slight advantage in these events. If you actually get really GOOD at these events then you REALLY have an advantage. Dan O’brien didn’t start beating Dave Johnson (or the rest of the world in fact) until he mastered these events. Dave didn’t have the speed or raw horsepower of Dan but he was very good in those three events (especially the Jav).
