This is a great web page, I watch it all the time as I prefer college athletics to professional. I don't know if it is viewable in all areas but it is where I live. The resolution fluctuates for some reason which can be annoying but it is good most of the time. Lots of games. Not much Hockey, but the others are well stocked.
