How do you feel about fake eyelashes and preoccupation with hairdos?
And parents who have to put their oar in?
The parents have to keep their distance. The coach can't deny them their right to post and tweet, but they can send subtle messages that their gripes are being ignored and are counterproductive to their daughter's success. And if the team is doing well, it just makes the parents look foolish and selfish.
The hairdos and makeup are a different story. The coach can indicate her preference and the players may adjust just to please her, but we don't live in the era when Wooden could tell Walton to get his hair cut or be replaced and Bill would furiously pedal to the barbershop before practice. Someone else pointed out that athletes have flaunted individual styles for decades, so as long as it doesn't affect game preparation or team chemistry (extreme attention-getting shemes that noticeably irritate teammates), probably best to put up with it. The Bulls tolerated Rodman in all his glory.
Heck, one of my favorite NBA players, Stockton, was as straight-laced as they come but wore the short throwback shorts. I think the main thing is to determine intent to see if this stuff is all about "me" instead of "we." Sam Feuring has her tattoo sleeve, and no one seems unduly bothered.
The upshot is that a coach can put up with individual body decorations that may appear tacky to the coach but doesn't affect their play or the team's. I'd draw the limit with uniform modifications. Players already have choices of hairbands, sweatbands, arm sleeves, long and short tees under uniform, compession shorts, etc. All kinds of style accessories to choose among without altering the basic uniform. A player might say she could pkay better if she tied her top into a knot and bared her midriff, but the coach should just say, "Tough cookies...deal with it."
Same with turning shorts into diapers, briefs, or hot pants. It has no useful function and just sends the message that the player's focus is misguided...whether it's Zaay or Sophie.
One positive thing for the fans is that the individual things do help distinguish players with similar body builds from a distance...whether they're an all-black unit or a group of blonde, pale-skinned young ladies from a Dakota team. I've seen some lower-division teams with all-Caucasian girls with silmilar hairstyles and body types, and I couldn't them apart until they had closeups.
Evidently, neither could the tv announcers.
