~~I'm not saying it's right or wrong but your son is going to be an outlier when it comes to the habits of college athletes. Most drink, party, etc. There are two ways to look at it...~~
@PABaseball - there's no question about it. Even on his HS team, most of those guys were partying and getting smashed drunk on the weekends. So, he didn't hang out with teammates off the field. He really has a small circle of friends who are like him - most people would call them health nuts. Don't drink. Don't smoke. Don't party. Very particular about what they eat. More interested in training than doing anything else off the field. His girlfriend is the same way and I know that's why they found each other. Seriously athletes who don't follow what most people their age are doing.
That's why I say he needs to figure out on his own how to deal with the situation. The world isn't going to change. He needs to figure out how to coexist with it.
