I remember seeing some highlight replays here and there, but I think it was mostly just during the cmuTV broadcasts. I looked through all the videos I had and didn't find any pushbar-specific compilations.
So, Merry Christmas, here's a quick one I put together!http://cmubuggy.org/video/missedpushbars0407
It's not comprehensive at all, and they're not all full quality, but it's what I could put together quickly. Also, I left out our 2004 A team missing the bar on finals because he wasn't close enough for it to be visually exciting and I'm in the frame having my hopes and dreams crushed at the last second.
