I recently rewatched Backlash 2001, and I must say the Raven/Rhyno hardcore title match is the best one I can remember off the top of my head. And I don't think I've ever seen a hotter crowd for a match for 2 low/mid carders. It's between that match & Raven/Kane/Big Show for me.
Rhyno vs Raven- Backlash 2001. Really great match with both men finding creative ways to use weapons in the match and the usage of the weapons making complete sense.
Speaking of Rhyno, I'm in the mist of doing a Rhyno project and in that project, I'm coming across a lot of solid Hardcore title matches from him. His Hardcore title match Chris Jericho on RAW 4/30/01 and along with his Hardcore title match against Test on Smackdown 6/14/01 are two fun Hardcore title defenses. Two good gems to check out for.
