Dan O'Brien is an all around athlete. He has proven it by simply winning the decathalon. The decathalon consists of multiple events. He is also the record holder for the events combined.

Probably one of the fittest athletes of the late 1990's. The decathalon is one of the most grueling events as a sport. Olympic decathalon usually determines the world's most fit athlete. He got too much publicity in the use for his sport, which probably caused him to lose a bit of focus towards his events. Overall, he was very fit.

He is the greatest athlete in the world, but he gets injured too much. I don't think he should be considered an athlete anymore.

Dan is a good athlete. He holds the the record for the decathalon. He does well at all events. This is why I give hima good rating.

His later successes can't fully repair his tarnished image from failing to make the 92 games. Remember that pre-Olympic hype, followed by him totally choking?
