I'm just finishing this site up. It's a Drupal site with quite a few modules. I didn't design the site, but I did incorporate a lot of the design into the theme.
I tweaked the Events module and completely overhauled the Taxonomy Menu module to fit the needs of the site. I also created an extensive and robust theme that integrates well with the dynamic content the site is designed for.
This is a social networking site designed for several teams. It's designed to be completely scalable, so it will work well for 10 teams or 10,000. I also worked hard to make it as easy as possible to manage and work with for the various levels of users who will use the site. Logged in users get a new menu to help them create content, etc.
Each Team has a calendar, a roster, and a coaches page, as well as advertisements they can upload and a blog. While it's certainly a Drupal site, it also doesn't look like an obvious Drupal site.
