I'm going to assume your son will experience this soon... but the world is full of groupies. I was shocked when I was first shown how some of these free-spirited-girls 'slide into players DMs'. It's also why most married Athletes have locked social media accounts (the wives don't like the random naked pic's sent to their husbands at 1 am).
The BYU roster has lost many players to these types of distractions due to the HC (Party girls and BYU don't mix).
A kid can be just as distracted by the flood of 'extracurricular activities' that attack them 24/7 as they can be distracted by marriage. However, most of the married players have wives that keep them focused on school and football because they are invested in that player's success.
I have been standing next to a player and had a head coach say "We need to get this kid married" with no humor in his voice.
