Who is the greatest American male Olympian of all time? To me, five stand out above the rest, but who's #1?
So subjective. In terms of "most electrifying", easily Spitz and Phelps. They dominated their sport across a broader range. Lewis and Owens were basically sprinters/jumpers. Oerter was one event, although he lasted longer and came home with four golds in foiur successive Olympic Games.
I will also assume this is limited to "Summer" Olympics. If you include Winter, then it really ISN'T close. It's Eric Heiden, hands down. Five races, from 500m to 10000m. Five gold medals. And not one of those races was in doubt past the completion of his first lap. If not for the Miracle On Ice, people would STILL be talking about Heiden.
I profess a certain bias to Carl Lewis. Like Larry Holmes with nobody to fight, Lewis had the 1984 races sewn up due to the absence of the Eastern Bloc. In 1988, he beats Ben Johnson a month before (after Johnson had been winning regularly and setting new 100m record in 1987). Johnson claims "going home to rehab injury", comes back juiced to the gills to set another "record". When Johnson gets caught (when he needed four beers to complete **** test, most knew the inevitable results), Lewis gets gold and record, but it's kind of anti-climactic. He then loses record to Leroy Burrell, loses chance at long jump record to Mike Powell (who basically has one "super jump", while Lewis has FOUR jumps over 29 feet at ONE MEET!). Doesn't make team in sprints after this, but still wins 2 more long jump golds. Pretty incredible. Hard to say how he would have done in 1980, as Eatern Bloc-ers were still juicing big, Lewis was not yet sprinting full-time, and he was only 19 years old. But he was already on the top rung of long jumpers in the US.
But another name is missing: Edwin Moses. Sets world record in 1976, victim of 1980 boycott, wins again in 1984, fades in stretch in 1988 and promptly hangs up the spikes. But what he did on the track is almost unmatchable, so thoroughly did he dominate. Moses lost his record to a one-race wonder (Kevin Young) who basically lost his step-count thereafter and never ran another race approaching the record-setting one.
