I worked for a D1 track and field team while I was in college and I found the Pent/Hep/Decathlon some of the most fascinating sports with how coaches approached which athletes to submit. Some coaches (like the one at my college) chose to submit true generalists, athletes that wouldn't usually win an individual event but would get points in most of them. But other coaches favored submitting athletes that had distinct specialties, assuming they'd win that event and then get points in a couple of the other events. It's been a while so I don't exactly remember which approach seemed to work better but I found the strategy fascinating!
