I'd agree, but i'd also have to say Benoit did a lot to help solidify MVPs position on the roster.
MVP and Ken Anderson both appeared on SD roughly the same time. They teamed together after their characters were established, and then both were given to SD's best veterans, The Undertaker and Kane, in order to get them over.
Now Anderson was doing a lot better than MVP imo, because not only did he have an outlnadish gimmick that the fans ate up every week, he was also going over ME'ers on a regular basis. He beat 7 former WHC in his first 6 months remember? So Anderson's credibility was building very well and people were talking about him as a golden prospect.
MVP however was working with a pretty crap gimmick, in that he was the most expensive free agent ever, even though nobody knew who he was, and wasn't chalking up major wins against anyone.
The Inferno match with Kane at Armageddon probably gave MVP's early career a major jump start. I feel he was struggling to connect with the crowd, but after he burned himself so severly, i think the fans respected him a bit more, and therefore paid more attention. I've always felt, that if you don't have great charisma or ring skills, taking stupid bumps is the only other way to get the fans' respect, especially in the Attitude era, since so many talentless nobodies got over by being the Hardcore champion i.e Steve Blackman.
Anyway.....
After fueding with The Big Red Monster, MVP then entered a US title fued with Benoit. They had a grand total of 3 matches, and i feel that Benoit brought out a lot in MVP and really gave him the chance to showcase his talents. Also add in the fact that their 3rd match was a 2/3 Falls match, where MVP won with 2 straight falls (something most fans would have never witnessed before) to win the title, over 'The Greates Technical Wrestler In The World..... er........ Then, and people were bound to take notice.
'Wow, he beat Benoit in 2 straight falls.! This guy's something to pay attention to.'
It's hard for a rookie to get over when taking on a Super Heavyweight imo, unless that SHW is someone like Undertaker who has speed and agility as well, because otherwise you've just got a 300lb of clay to fight against for 10 minutes. IF you've got unlimited stamina and strength like Cena or Batista have you'll do fine, but if not, you're always going to be limited to taking a pounding, and working the legs, which slows down the match pace, and audiences lose interest fairly quickly. By having the gimmick match where MVP was able to show how tough he is, and then moving on to wrestling someone with a similar style and build, complimented MVPs skills a lot more and he was able to show us what he could really do. The only guy who could complimented his style better would probably have been HBK.
Now that he's going to start fueding with Punk, i think we'll see a side of MVP that we haven't seen since his fued with Benoit.
