The problem is, instead of using an experienced mouthpice to help an inexperienced talent/unfamiliar gimmick get over, they use inexperienced talent to help total unknowns to get noticed and it doesn't work because neither of them are able to help the other out. Or they put 2 random people together and they don't do anything.
Lets take a number of talent who in the last 2 years or so, have had managers.
1. MNM - Now originally, Johnny Nitro appeared on TV a couple of times, even in a backstage segment at WM20. Then a few months later he's in this tag team with this smoking hot chick following them around. They win a few tag titles, and then people stop caring. The team split. Melina and Nitro (in a relationship at the time) carry on together, Mercury gets nothing and falls of the map completely. Nitro wins the IC title (big whoop these days) and Melina screams a lot. We have that brief K-Fed bullshit, and then it's over.
Then Mick Foley is fueding with Ric Flair and Melina is suddenly following Foley around. After that ends, we end up with Melina on her own, and suddenly she's the only one that's over and Nitro doesn't get a lick of interest his way until his fued with Punk starts to heat up and is then relegated back to tag teams.
What was the point of this team and their valet? In the end, the most succesful one of the bunch was the valet! The exact same thing can be said for Michelle McCool. She started being a valet for some tag team, and i'm fairly certain they're both released and she's still there. Of course, this also started when Trish debuted and the only reason the people at home watched Test and Albert wrestle as a team was for Trish. She became the most succesful Diva ever, and neither of them (who started before her) were still employed in WWE today.
Duece and Domino - Here's a similar situation, except none of these three made any head way at all. What was the point of Cherry exactly? Did she ever speak at all during their run?
Santino Marella - Why he needs a manager i don't really know. He's comedic gold. Granted i love Glamerrella, and both Beth and Santino have flourished as a result of the pairing, but it's not Beth, nor was it Maria when she was partnered with him, that got him over. HE got THEM over. Despite being an active wrestler, Santino has been one of the best managers since.......
Umaga - UUUUUUUUUUUUUUMAGAAAAAAA!!!!! Armando was awesome (he's also who i was referring to above). Unfortunately they got rid of him, because people enjoyed saying UUUUUUUUUUMAGAAAAAA too much. Pure bullshit. Umaga has suffered a great deal since Armando left his side.
Khali - Well, first he had Davairi and now Rumjin Singh. TBH if he didn't have a manger of some sorts. He'd be worse off than he is. I personally enjoyed Singh translating Khali's threats and watching him crush things with his bare hands. That actually made me forget how terrible he is in the ring. Sadly his health has put a stop to these 2 in terms of wrestling success goes.
Mike Knox - Again, much like MNM, D&D and T&A, the only reason to watch the guy was for the eye candy hanging off of him. They had a little stint of him fighting people who tried to chat her up, but that didn't last long, and now he's got to rely on his beard to distinguish himself from the rest of the crowd. I'm sure that Kelly has had more screen time than Knox has.
William Regal + Layla: Let's see. She was being hounded by Jamie Noble, she told him to get lost and joined Regal and her mouth hasn't opened since. In fact in the 3 or 4 months since then, she's thrown a shoe at Punk and that's literally it.
Mark Henry and Tony Atlas: Again, the guy talks at first, and actually, wait, wait, INTERFERES IN THE MATCHES AS WELL!!!! Atlas and Santino must be the only people i've mentioned so far that actually try and help their counterpart win matches. However, the two have stopped talking since then and people are getting bored of Henry again.
The Burchills - I know they had an angle set up that didn't work out, but that doesn't mean put the pair of ECW so that none of us can check out Katie Lea. These 2 are being buried, plain and simple.
Tyson Kidd and Natalya - IF YOU'RE NOT GOING TO GIVE US THE 2ND HART FOUNDATION, STOP WASTING NATALYA'S ABILITIES!!!!! I know they're a couple a well, but that doesn't mean she shouldn't still be on SD, trying to make McCool and Maryse look half decent in the ring.
All in all, with the exception of Khali, Umaga and Santino, none of the managers have been any real benefit to the talent (unless they got to sleep with them later). Gone are the days where you could have somebody like Heenan get 4 or 5 separate guys over within the same company withing several years.
Take Paul Bearer for instance. Not only did he help Taker for years, he got Mankind and Kane over and even worked with Vader for a while too. ALL main event talent in WWF. Sure Vader was there already, but the other three sure weren't were they?
I doubt we'll ever see a pair like Taker/Bearer, Lesnar/Heyman etc ever again tbh. We'll just get random talent thrown together in the hopes they help each other out, but never be put in a programme or given a microphone to do it with.
With the exception of Santino and co. WHAT IS THE POINT OF HAVING THESE PEOPLE TOGETHER?
