"Coming back for his first practice his junior year, having won a title the previous year, Walton decided he wanted to wear his hair longer than what Wooden required. Walton walked into the gym and Wooden said "Bill, your hair is too long." Walton replied "Yeah, I'm not going to cut it." Wooden just stared at him for about 30 seconds out and then said "Well Bill, it's been a pleasure having you on this basketball team. Enjoy the rest of your time here at UCLA."
Said Walton, "You know, Coach, I have the right to have facial hair."
Coach Wooden answered, "Bill, I know you do. How strongly do you feel about that right?"
Walton answered, "I feel very strongly about it, Coach."
Then, Wooden replied, "Bill, I admire a man who stands up for his beliefs. We're going to miss you this year."
At that point, Walton got on his bicycle and peddled to the nearest barber shop and had his face shaved.
When he returned, he HOPED Wooden would let him back on the team.
As the years went by, Walton continued his relationship with Wooden and called him every week to see how he was doing.
It's not about whether hair is a problem or not. A team is about more than just showing up and doing drills. There are fundamental elements that different teams build on. Not every team requires such things, but some do. The Yankees made Johnny Damon shave and get a hair cut. The coach makes the rules. If you don't like it, too bad.
