Anytime you have the oppurtunity to observe another crew, make the best of it. Take the things that they do, right and wrong, and use them to better your game. If you know these guys well enough, you could give them some constructive critisizm by approaching them the right way. You could start a conversation by saying something like "Hey Joe, I saw you the other night at the East vs. West game." If he says something like "Yeah, how'd we look?", then he's opened the door to hear more. Make sure it's not all negative. Have some positive stuff mixed in. I wouldn't go over their head though. More than likely, you would end up regreting that. Either way, it's always good to learn from other's mistakes whenever you can.
