Yes because Nick Bockwinkle, Andre the Giant, Curt Henning (world champion before Bobby managed him) and Ric Flair (7X world champion before Bobby), were never going to be over or get over without Heenan. You are kidding right? Bobby wasn't any better than Paul, not trying insult him here but comparing his era to anything paul is doing is completely different. Punk didn't need Heyman, fine, but he enhanced his character. Same thing that Heenan did with Flair, Or Rude, or Henning, or Bockwinkle, or Andre. Frankly, He enhanced them just like Heyman. I like Heyman more, I think they are equals mostly because it was easier to do the job back in Heenan's era.
I disagree..it IS MUCH easier to be a manager today. There is no competition. How many actual managers are in WWE today ? Maybe 3 total, and two of them are pure characters in mid card feuds with undercard talent (Lana & Coulter) ? The last main event mgr WWE had before Heyman was probably Flair during the Evolution days but he occasionally wrestled.
Heenan prospered in an era where managers were extremely important to the storylines, they helped drive storylines in a way they almost never do (aside from Heyman and for a bit Coulter) do today. Im not even sure Id say Heenan was the best in his time, "Classie" Freddie Blassie, Capt Lou Albano, Gary Hart, those guys could get broom sticks over as legit main event level talent with fans. Jim Cornette for my money was the most entertaining manager of the time, he was pure gold every segment and excelled on the mic better than most of the wrestlers in those days. Cornette also was convincing as an ice cold, menacing villain as much as he was as a comical one, a hard transition he did with ease.
Lets not forget JJ Dillon, great presence, great mic work, Dilllon was a guy who became associated only with the best talent. When Lex Luger came up from Florida a big part of his storyline was that he believed the best way to get to the top was to work with Dillon, he managed champions. When Barry Whyndam had his famous 1988 heel turn it was the same reason, Dillon was the guy who got the most success for his guys, do you want to fight against him or join him ?
There were other popular and effective managers back then as well, including Paul Jones, Precious, Sherri Martel, & Elizabeth among the women (you could maybe argue Precious was more a valet llike Baby Doll and not a full fledged manager, the other two were clearly seen as managers), Woman, not too mention Jimmy Hart & Paul Ellering, two of the biggest names in 80s wrestling back in the day. Ole Anderson, Slick, Teddy Long, & Kevin Sullivan also had turns.
For Heenan to stand out as he did in that crowd was pretty impressive, that was a huge crowd with a lot of contrasting characters and styles across different promotions. Heenan, along with Dillon, Hart, Ellering, Blassie, Albano, & Cornette were clearly the most successful in terms of the constant high profile use in major storylines and performance on screen. Heyman actually started in this era, back in the mid 80s as Johhny Dangerously, the cell phone wielding cowardly business man style heel, a cross between the Hennnan/Dilllon man of distinction role & Cornette's comical evil genius role. he came up and worked for several years in this era, comparable to Sting & Lex Luger coming up at the end of an era dominated by Hogan-Flair-Savage-Dusty. They made a mark at the end of that era and continued on for several years. Heyman did the same.
I think post WCW, when Heyman was in ECW he altered his style and character a great deal and it worked, made him more believable and less hokey, the fore runner to what you see today from him. I give him credit for making that transition, that's not always easy to do.
When you look at how great Cornettte was it's hard to just crown Heenan the best of his era. Dillon too, and Ellering, they were exceptional. Heenan definitely makes it to the finals though. Today, with so few managers on the wrestling landscape and even fewer getting significant air time and storyline positioning at the top tier, it's much easier for Heyman, who's been managing so long he lasted Shawn Michaels entire career and retirement, managing so long his career is longer than Undertaker's (his big start came in 1989), to look great, head and shoulders over everyone else. He is good (he adds a lot to the relatively bland Lesnar and covers well for his many absences) but he faces a lot less competition than Heenan did.
