I had some time to chill out and I agree with you, by and large, but here's what gets me:

You can totally differentiate between someone who has excelled at a physical sport. It is apparent in posture, economy of motion, and honestly even pure physique. I did 10 years of competitive ballroom dance at least 10 years ago now, and I guarantee even I could have made a better show. That is not indended to be a humble brag: im pushing 40 and kids tore up my physical prowess lol. I CAN stand up and full space though, and move with my whole body in an intentional way. The selection pool, even if there is not a breaker scene, could have been widened to include people who wouldn't look ridiculous even with exactly the same routine. It's just totally wild lol.
