IMHO, making everyone else look bad is about the worst thing you could ever do. It's highly unlikely that your manager will carry more weight in 10 (or even 2)

IMHO, making everyone else look bad is about the worst thing you could ever do. It's highly unlikely that your manager will carry more weight in 10 (or even 2) years than everyone else you've ever worked with. Beyond that, your coworkers are a lot more likely to be your friends than your manager. Basically, if you want to look good, do really great work and bring as many of your coworkers (and hopefully friends) into the fold as possible. When you're willing to share successes, you end up having a lot more of them, and credit will find its way to you.
