That's great! Good for him. He'll have a bunch of money saved up when he gets done.
I have heard of some NFL player who was driving his old beater car from college that someone gave to him for free. He didn't want to spend all his rookie contract money on a car, so he kept the old one. That's so cool to hear stories like that because they're people who have good heads on their shoulders and they're making something of their life. It's fun to root for them to succeed!
