I came across a site (which I am using right now in fact)
its called www.digitalfieldtheory.com, no idea who or why they created it but its exactly the same as buzzerbeater.com
Story is that I (as a high school student) was given a laptop as a new digital education revolution scheme. In order to stop students playing games (as these laptops were for educational use only) they blocked many sites out including buzzerbeater.com, and by luck I stumbled on digitalfieldtheory.com and use it whenever I am on my school-provided laptop.
