I will personally suggest Mambo, which I used for my team's website. (http://www.dublinrobotics.com ) It has a bit of a learning curve, but once you get the hang of it, it is very flexible and there is quite a bit of community support for it.

When I was getting ready to redesign our website, I debated writing my own PHP/MySQL system as well, but decided against it. Perhaps the main reason I decided against it was the fact that I am a senior this year and will not be around next year to help out with the site should anything go wrong or if they want to add on to it. This is the main concern you should look at when deciding what to do. How easy will it be for my team to use and update the website without my assistance?

Just remember that there is not a one size fits all answer. Pick what you think will work best for your team, not necessarily what others suggest. Your website should be a method for your team to communicate, not just another thing to do for an award.
