How does an X-Pac and Kane team work where a R-Truth/JoMo team doesn't?
Simple. People cared about X-Pac and Kane BEFORE they became a tag team. JoMo has his followers, but can you really say R-Truth has enough fans of him and his character and not just his theme songs?
In both instances, two random wrestlers were thrown together to make a tag team because enither guy had anything to do at the time.
Kane and X-Pac (I don't know this for sure, so i am assuming) probably had an actual angle or segment worked out where one of them had been beaten up by 2 guys, and then the other one was attacked by the same two guys, and the first victim comes down for the save, then suddenly there's a tag fued.
With JoMo and R-Truth, they were thrown together in a tag match, and WWE decided to just keep doing it over and over again, and we the fans think we've got a new established team, based on the fact they had a tag title shot once.
Do we all consider Evan Bourne and Mark Henry to be a tag team?
With Cody and Drew, prior to that Tag Gauntlet match at NOC, did anyone actually identify those two guys as a tag team? Or were they just two guys who were beating up Matt Hardy and Christian every week, an angle they unceremoniously decided to just stop half way through?
JeriShow was nothing like JoMo/Miz or any of the other random tag teams we've had in recent years.
When JoMo/Miz were thrown together, they won the tag titles in a random tag title match on SD that was actually part of the MVP/Matt Hardy fued going on at the time. This wasn't done to create a new tag team, it was done to get the belts OFF of Hardy/MVP so their US title fued could continue. 3 nights after this Miz and Morrisson were wrestling each other in a triple threat match with Punk for the ECW title!
Then they started getting these stupid online shows and Miz and Morrisson were able to show off their mic skills and get over through that, and THEn they started fueding with guys like DX, after they had already proven that they were worth more money as a tag team.
Now let's look at JeriShow in comparison:
-2 ME heels. That's ME heels that people actually enjoy watching.
-Chris Jericho is still giving the best promos in the entire company at this point, as Punk hadn't gone fully blown heel at this stage. He's also had a red hot fued with Rey Mysterio recently, so seemingly everything Jericho is touching is turning to gold.
-There was interest buzzing around Jericho well before they became a tag team, because he and Edge were team mates first, and Edge got injured and we had a month of 'Who's Jericho's new partner?' And even when it turned out to be Big Show, people were still interested because of the mic work, and the whole total coward Jericho + One Punch Big Show dynamic they had going on PLUS the awesome mic work.
-They were on the PPV card EVERY month. You can't even say that about Drew and Cody, because they didn't wrestle at HIAC and apparently won't be wrestling on Sunday either. Do we really need LayCool v Natalya two PPVs in a row?
Let's take some more examples that worked:
Taker/Big Show - Again, two ME heels that everyone wanted to see, put together because Show hated Kane, Taker hated Kane for betraying him and hated X-Pac for being the reason behind it, plus X-Pac cost Taker the title at Fully Loaded '99. Kane/X=Pac win the tag belts, Show and Taker decimate them immediately after.
The 2 biggest, most evil guys on the roster at the time pair up. Who the fuck is going to stop them? Straight in a tag fued. Job done.
Rock 'n' Sock - Honestly i can't even remember why these two paired up to begin with, but again, ME faces everyone wants to see with great mic work and chemistry, went straight into a fued with Taker and Show.
Two Man Power Trip - Again, the two biggest heels pair up with the full backing of the boss. Was done to fully cement Austin's heel turn. Not only did he shake hands with Vince, he's also tagging with HHH, the man who tried several times to cripple Austin. Crushed the Rock, beat up just about everyone else, straight into a fued with Taker/Kane.
Rated RKO - 2 ME heels (noticing the pattern yet?), came together because both of them absolutely hated DX, went on to fued with them immediately.
Legacy - Everyone wondered who Ted Dibiase's tag partner would be, and considering that he hadn't even wrestled prior to that tag match, people were wondering what Dibiase could bring to the table. Once Cody turned on his own partner, to win his own tag titles, people wanted to see what was next....... turned out it was nothing, but then guess what? A ME'er was added to the mix in Randy Orton, and they became relevant again.
And then there's the pairings that came simply from two guys who'd fueded repeatedly, and then circumstance put them in a tag team i.e. Jericho/Benoit tagged to defend themselves from Austin/HHH, Benoit/Angle forced to take part in a tag tournament by Stephanie tec.
Now here's examples of ones that didn't work:
-Renee Dupree and Kenzo Suzuki. How many of you even remember who Kenzo Suzuki was?..... Exactly. Renee had failed to get over as a tag team guy. He failed to get over as a singles guy. They then put him in another tag team, and they BOTH failed.
-Sylvan Granier and Rob Conway. Conway basically filled Dupree's spot and assisted Granier in NOT getting over as French invaders.
-William Regal and Dave Taylor. Who the fuck is Dave Taylor? Exactly......
And then there's the guys who got over, but it's obvious it was nothing to do with them being a great tag team. These include:-
Billy and Chuck - Could their extremely flamboyant manager Rico have had something to do with it? Because surely it wasn't the bleach blonde hair jobs and the Nsync backing music that did it, and Chuck's wreslting ability definitely didn't have anything to do with it either. Rico's character was the only interesting thing about his tag team with Charlie Haas as well for that matter.
T&A - Obviously because of Trish. Notice how no one gave a flying fuck about either of them once they'd split up.
Head Cheese - Got over as comedy relief, not as a decent tag team. Santino and Kozlov are the modern day equivalent except not as funny.
Benoit/Ryhno - Tagged together because both had suffered broken necks. Now that's a good basis for a tag team if i ever heard one. 'Hey we've got the same weakness. Wanna be a tag team?'
And then there's the guys who got over purely because they were apparenlty related i.e. The Hollys (debatable whether they actually got over or not. Crash did, people seemed to just continue tolerating Bob) or the Guerreros, or the Bashams (again, could have just been wasshername from Tough Enough with the bondage gear that made them stand out, because once she was gone no one cared anymore)
