All of these threads are getting ridiculous. THe faint outrage from the snowflakes is getting old.
Weight, haircuts, gear and any other thing a "coach" can control that improves performance is being looked upon as bullying and manipulation.
These are professional coaches and athletes. If cutting your hair makes you faster (I have always thought that Hasay hair was an issue), then you do it. Companies have millions of dollars invested in this.
If the owners of the NBA/NFL/MLB demand that you keep clean shaved or that its mandatory that you lift weights then you do it.
