Across all sports in all countries, who is the best team or player of all time?

Speaking in terms of pure talent, might be Shohei Ohtani. I know he hasn’t really played that long, but I can’t think of any time where someone has played two completely different positions in a sport and was elite in both.

Otherwise, it’s comparing apples to oranges. Every sport has their own best players and best teams of all time.
