5. The Hardy Boyz vs. The Dudley Boyz - 2000
The 2000 Royal Rumble is probably my favorite non-WrestleMania PPV of the last 15 years... and the Rumble itself wasn't even that great. This PPV is absolutely stacked and this match is a true highlight. One of WWE's best 2-on-2 tag matches of the 00s and still holds up today, despite being an Attitude Era brawl. These guys definitely killed each other and while I won't complain that WWE's moved away from this style, it is a really fun match. Those damn chair shots to the head are incredibly hard to watch now though.
It was really a coming out party for both teams. The Hardys proved they weren't one-hit wonders with the No Mercy ladder match and the Dudleys avoided a disastrous Public Enemy-esque flop. Not sure either team would've become as big as they did in WWE without this match.
