Problem is this isn't some intern at some shitty company making shitty money. These are athletes, being paid very well, with numerous professional coaches who have been around the league for quite a long time with them there when they need them. There are also many many more players on the team, some of which have also been around the league for quite some time. Let's be real here. These players either want the money and the bright lights, or they want the game and to cement their place in it's history.
It's the same philosophy. You hang around your fellow players way more than the coaches. If you have a fellow teammate backing you up, it makes a big difference.
Bottom line, players have a higher probability of succeeding when they have another player who is ready to show them the ropes. That philosophy goes with anything anywhere you go. Environments influence people.
