I have a hypothesis.
Is a sporting legend worthy of the title if their sport has high barriers to entry? Also if large barriers exist how can we be sure that they are the even one of the best?
For example many would agree that Aryton Senna was one of the greatest F1 drivers of all time. Given the barriers to entry is it feasible that the greatest F1 driver never drove a car?
A more extreme example would be showjumping. Is the Olympic champion really the greatest or are they simply the best amongst those with access to stables and horses worth huge sums.
Contrast that to other sports with very low barriers to entry. Running for example (my sport)
Does this mean that Haille Gebrselassie really is the fastest marathon runner of all time given that those with the ability, drive and commitment to beat him would likely have shown their hand by now.
Does it mean the latter has more of a claim to be the greatest (in their discipline)
