I wouldn't put Bret/Shawn in the top 10 (maybe not even top 20), let alone the top 5. There really wasn't ever much of an onscreen feud at any point in their history.
Let's look:
- They did the Survivor Series 1992 match without any real buildup.
- The WMXII match was face/face, and they were kept apart for the most part until the match.
- They were supposed to do the KOTR 1997 match until Shawn got "injured" again.
- And in late 1997, Shawn was the ref in Bret's 5th title win, but he was paired with Undertaker until the big Survivor Series 97 showdown.
Sure, there was lots of behind-the-scenes stuff going on, but not much that the fans could get into as far as a feud.
Hogan/Orndorff deserved a much better writeup, too, given that Orndorff was Hogan's beiggest feud in terms of money drawn.
