The Road Warriors vs. the Powers of Pain
 
Tully Blanchard and Arn Anderson vs. The Midnight Express. This is one feud that stopped before it got started. I was ready to see Tully and Arn battle Booby Eaton and Stan Lane. Before you knew it, Tully and Arn were gone. I also wanted to see JJ Dillon and Jim Cornette go at it. I was so pissed when Arn and Tully left the NWA, I really felt they belong there.

Not necessarily a feud, but Crockett(and Dusty?) dropped the ball big time on that incident between Flair, the Horsemen, the Russians, and Dusty.  Flair was wrestling Nikita in a cage, and Ivan and Kruschev interfered. Dusty ran in and saved Flair, which obviously was a shocker. Then the Horsemen came in and they 'injured' Dusty.
 
Talk about missed opportunity. A Flair-Dusty union(regardless of its length) would have sent shockwaves through the wrestling world. Instead, we just got more Dusty vs Flair crap.
 
 
Crockett never realized how great his product was. So superior to what WWF was offering in the mid 80's, but he mismanaged it. Regardless of booking issues and things of that nature, NWA should have went national in 1985. Staying on the east coast was pure idiocy and its no surprise Mcmahon eventually monopolized the industry. I remember watching NWA/WCW and just dying to go see it live(I live in Cali). Nope. Not a chance. Instead, people in Cali went to arenas to see Hogan fight Bundy, Moraco, Studd,etc.
 
Regarding the Midnight Express and Tully and Arne, I remember the exact moment that first happened. My cousins and I were at the arcade/pool hall and they had wrestling on their tv. The Midnights confronted Tully and Arne, and every single person in the building had their eyes glued to the screen for that segment. Once it was over, everyone went back to what they were doing.
 
Like I said, missed opportunities. If one arcade full of people of all ages were interested in that, it was probably like that everywhere. Also, whenever major events would happen, the whole school would talk about it for days, including the teachers. Wrestling was magical back then and pop culture was embracing it. Crockett just let it rot on the vine when it should have been thriving.

I would've loved to have seen Dusty work with Ron Garvin when Garvin turned on Dusty.  Didn't Garvin go to the WWF a few weeks after he turned heel?

Flair and Hogan in 1991/92 in WWF!  How could Vince have not capitalized on that!?!?  That should have been the biggest match of the decade!

List:
 
Magnum TA vs. Jimmy Garvin (unfortunately got cut short due to the accident but would have sent him into the deal with Flair)
Road Warriors vs. Powers of Pain
Tully/Arn vs. Midnights
Midnights vs. Original Midnights
Manny Fernandez vs. Jimmy Valiant (he did the turn but not too much after that)
Dusty vs. Ronnie Garvin
Barry Windham vs. Bam Bam Bigelow
 
On the Flair vs. Hogan deal:
 
I agree, this should have been built up to Wrestlemania. I would have hada few verbal confortations without them touching until maybe Royal Rumble time in the Rumble in order to build up the match at Mania. I think Vince was thinking $$$ signs early as I think the business was in a decline at that stage and wanted to put the match on at house shows early. But realistically, he could have done the rematches after the mania match and still did good. That is the way I see it anyhow, it could have went down differently than what I think.

I know, by the time Flair and Hogan faced one another in WCW, the dream match lost it's luster. It should have been done at Wrestlemania VIII.

I agree.  I also think that to give the match credibility they would have had to have had Hogan job to Flair.  After all most WCW fans were NWA fans that continued to watch as it turned into WCW.  They had their favorites such as Flair, and the WWF crowd had their favorites such as Hogan.  So when you bring the former WWF Champion into WCW and have him beat Flair it's like telling the fans WWF was better all along; that WWF had the best wrestler.  They should have known that would anger WCW fans who had looked to Flair as the best in the business since the early 80s.
 
Then they wondered how why Hogan wasn't getting over as a face!!!  Eventually they were forced to turn Hogan heel.

The WCW matches were only 2 years later. I wouldn't say it was an issue of being "past their prime" as much as (as another already pointed out) the luster was gone. It didnt feel like a huge, gigantic match, like it would have in WWF.
