Vince'll push who Vince wants to push - to say that Race and Rhodes were not known is laughable, the territories were only just taken over by Vince and JCP and most fans of any age would know their NWA champions because it was their job to move around the NWA territories (incl WWWF). Hogan, Flair and SCSA have all been given the world strap when they've been in as bad if not worse physical condition than these two wrestlers.
The arguement that Vince is first and foremost a business man is valid, but when you look at things like the WBF, XFL, the World or WWe Films - all vanity projects... Vince doesn't always let his brain rule over his ego.
Pushing Flair and Goldberg were no brainers - both were that rare thing, wrestlers who were well known outside of wrestling fans. Lesser recognised former world champs like DDP, Booker, Race, Rhodes, Luger, Christian, Truth, Steiner, Rhino etcetra were all made to look like non main calibre.
Mid and lower mid carders from the competition were given a fresh start and pushed with creative tweaks (ex UT, SCSA, HHH etsetra). Punk might be basically Punk but it has taken time - he famously has been criticised for not being able to work and has been knocked down for public comments (as have MVP, Hardy and Carlito), but the massive heat he always generates has always eventually overcome these problems. Another way to get depushed to show outside interests (see Mickie and to an extent Y2J) because Vince demands complete dedication from his independent contractors.
No one can argue Vince's pedigree as the greatest wrestling promoter ever, but the character Mr McMahon is recognised as not being to far from the truth.
Sorry my friend but you are dead wrong here... in the late 80's Vince was not interested in the guys who would know who Harley Race or Dusty were... anyone he wanted from the territories he got before 87... The vast majority of WWF fans were kids who bought toys, ice cream bars and T-shirts... They wouldn't understand territories, that there was an NWA or AWA just that Hogan, Piper,Savage, Warrior, Andre and DiBiase et al were the big stars...
For a guy like Rhodes to come in so long after meant they had to decide right away what he was coming in as... Was he Hogan level in ability... easily 5 years prior, but now he was ageing, slower and in general popularity and appeal nowhere near... So they brought him in a level below, as someone who clearly was special , he got his own superhero comeback slot but not on the level of a Hogan or Warrior... He could be beaten... To help him integrate he was given a manager in Sapphire that kids would like and the "American Dream" moniker/Music/gimmick so parents could get behind him as being someone they and their kids could both be fans of...
NWA fans would not have approved, but it was the best he was ever gonna get at his age and in the WWF at that time... he took the money happily for a short run, won big matches against main eventers and helped his boy's career get started... fair treatment I'd say for someone Vince's dad never particularly cared for...
Race would even less have been known by the kids... their dads may have told them about his past but again when you are a kid and all you know is Hulk Hogan is THE champ, 7 NWA reigns before you were born, somewhere else that what you know doesn't instantly translate... Race had also not been especially cordial with Vince and Hogan during the expansions, even being alleged to have threatened to kill them if they ever ran in his town... only to come and ask for a job when they actually did... Harley was known for his killer rep and bluster and hair trigger temper but was still given a gimmick that reflected his greatness and elder statesman reputation... rather than the psycho or washed up has been gimmick he could have ended up with... he was the king till he couldn't carry that honor... The kids never liked him cos he was booked to be the horrid old guy who beat up their heroes... he was the evil headmaster of the WWF...again for Harley at the time, more than he could have dreamt of... Vince could easily have not used Harley or Rhodes at all and the WWF would not have suffered one bit... indeed some other talents might have got better pushed like Rude and Martel...
Both these guys had nailed their colours to the mast early by not being cordial with Vince Sr by mainly doing business with rivals... and that Vince Jr later did business at all was something in itself...but these men were legit former World Champs...
But you have to remember that World Championships then were a dime a dozen, the AWA had one, NWA had one, World Class had one... they were not ALL the same level as Hogan and his WWF belt in either popularity or calibre of draw. AWA World Champions were brought in as strong mid carders and in reality that was their level... Rick Martel and Curt Hennig were brought in strongly but at their appropriate level for the time...they grew well into the WWF system and got pushes... Sgt. Slaughter had the benefit of his previous run with the WWF and the Gulf crisis so he jumped the queue...
Some NWA World Champs were short term ones like Ronnie Garvin and Kerry Von Erich... no way should they have come in as main eventers... but both got strong mid card pushes out the gate, even though Garvin's was short lived... Steamboat was only a world champ after he was big in the WWF, so why push him straight to the main event on his return they knew he didn't need to be there to tear down the house... That Ricky didn't quite deliver is as much down to him as Vince...
As time went on the number of belts went down but the quality of former champ didn't go up... the ECW title was NEVER a legit world title... even most alumni admit that their TV title was more of a draw with RVD than any of their champs... to a man the ECW guys came in strong in mid card roles... many in the invasion... DDP and Booker T came in to title pushes but not the main one... the only time the WCW belt ever got to the similar levels as the WWF was 96-98... Goldberg, Hogan... whenever they came they got the main event... The only ECW guy who was ever "held down" was Shane Douglas... and that was cos of how he'd behaved in his previous run mainly...
Guys like Scott Steiner and Douglas, like I said before did it to themselves... Vince WANTED to push him in late 93/early 94... First a feud with Rick, then to a World title feud with Bret... but Scott didn't play ball... he wanted too much money and refused to fight his bro... so why would Vince give him a World title when someone else made (supposedly) money off that feud? He wouldn't... Shane chose to leave the WWF right when Vince was going to push him as The Heartbreak Kid, ostensibly cos his dad was dying... that he then signed straight up with WCW screwed him... of course Shawn was gonna bury the guy who was first choice for his gimmick at every opportunity... and why would Vince help him after letting him down?
Finally, I disagree that outside interests are bad... they just have to be good for WWE... The Rock's movie interest didn't hurt him... while it served WWE's purposes of course... likewise Piper in They Live, John Cena's Rap Album and yes Chris Jericho's outside interests... In the main Jericho's outside work has been great for WWE... people know Jericho from the singing show he did, from VH1 segments, the Benoit fallout...from Downfall, Fozzy and MacGruber... and all the time their first connection is Chris Jericho he's the WWE guy wow he can do x too...
Where problems arose this time around was more to do with the injury issues WWE had at the time rather than how Chris did anything... WWE allowed him to negotiate and to sign up to the show, then suddenly Taker and others got hurt or suddenly didn't resign (Batista)... So they would have preferred him not to do Downfall at that moment... but it worked out as they now have new main eventers they wouldn't have had otherwise... Mickie James, Maria, some others didn't do things the right way and were let go for it...
Remember though Vince learned a hell of a lesson the day his dad let Hogan walk cos he didn't want him to do Rocky III... who knows where that TV show/Movie role will lead to?
