There are likely many, many instances of players that have been doing this or did it in the past for years.
Being a professional athlete gives you a sense of power and status reserved only for movie stars and famous musicians. You have the ability to manipulate vulnerable people in ways that are simply impossible for 99.9% of others - and I am certain a portion of them cannot handle that power without abusing it. Athletes should honestly be constantly in some kind of professional therapy at all times, especially junior players (they are in development years).
Getting away with actions like this embeds deep in your subconscious that you are able to get away with doing things that nobody else would. That reinforces the behaviour and teaches you that there are no consequences for your actions.
Just a huge stereotype. Creeps come from all walks of life. Saying it is particular to pro athletes is simply dumb and I doubt you have any evidence for this.
