1. Chris Benoit/Kurt Angle
Benoit & Angle, arguably the two greatest wrestlers in the sport today, always have awesome matches against each other. And the fact that they had to become a tag team made the feud much more interesting.
2. Triple H/Shawn Michaels
2002 saw the Heartbreak Kid's return to the WWE, which led a tough feud with Triple H and Shawn's first WWE match in 4 1/2 years.
3. Steve Austin/Kurt Angle
This got started in 2001 and continued in 2002. Before Austin's departure and the roster split, these two got on each others nerves ("What?") and got to have some great confrontations.
