If the program he's going in to is halfway decent, they'll cover the topic of his circle of friends, making new ones, staying out of compromising situations, etc. Its not about just getting off the drugs. One can get away from just about anything. But when you plunk yourself right back into the same situations as before, you're not going to stay out for very long. Sure, there may be exceptions to the rule, but they're just that...exceptions. Your brother already has several pluses on his side, that I can see. First, he has parents that loves him and is willing to make the hard choices to help him. Don't ever think this is not tearing your folks apart inside. Secondly, he's got a rather remarkable brother who has enough influence in his life so that he was able to talk him into going into rehab, on his own choice, rather than being forced. He looks up to you, Harrison. That places a tremendous responsibility on your shoulders, and from what I've seen, getting to know you here, you are more than capable of handling that load. You love football, and are willing to give that up for him. Not many would do something for a brother (I would actually suggest encouraging him to pick a hobby/sport of his own, whether it be football or Tiddlywinks, and get involved in it...that's a great way to fill idle time...idle time is not really a good thing for him right now, too easy to slip back in to old habits). Third, he's got friends. As you said, there are those who have come forward wanting to help. Friends, true friends, are what he needs now. Encouragement, whether it be the latest joke email or a quick "hey, bud, whazzup?" in the hallway at school, its what will let him know he's not alone. Its not going to be easy. But he's got some tremendous advantages going for him already.
