I mean there's stretches of the imagination possible for each of
  them: Swimming - fastest time: First body through makes a Hole
  in Time that the others follow. Takes some poetic license, then
  again, it takes even some imagination to see a hockey puck as a
  ball, although less.   == Well I wouldn't say _meaninglessness_
  - my brain is always always in this realm:
  [1]https://en.wikipedia.org/wiki/Topology since I first heard
  about it in college - 1990 or so - and spacetime is easily
  included there. But yeah, for practical, "back to planet Earth"
  purposes, I think you're right: Outside of outliers like
  synchronized swimming (which could be considered "clone sport"
  as are things in "pairs", Team Sports seems to fit the model of
  an "ball in the hole" idea, by morphing the ball and the hole
  but otherwise quite compatible.
