[quote name='mogamer']Retiring due to not being able to keep up with Daniel Bryan's level means that 75% of WWE's roster would have to leave the biz.

[/QUOTE]
Can't believe I tallied this, but I needed a break from work. Here'a we go!
CM Punk, Billiam Regal (William Steve Bob), probably Santino Marella, Goldust (Se7en), TJ Wilson (Tyson Kidd), Matt Sydal (Evan Bourne), Eddie Colon (Primo), Alberto Del Rio, Dolph Ziggler, Low Ki (Kaval), The Undertaker, MVP, and perhaps Fit Finlay (Finlay).
That's 12--out of WWE's 60 male wrestlers.
So, if my poor match skill is correct, 80-percent of WWE's male wrestler roster would need to pull a grenade pin and swallow an exploding pineapple.
Assessing other wrestlers, I see Joe Hennig (Michael Lotsoluckycharms), Windham Rotunda (Husky Harris), and Wade Barrett improving significantly in the next few years. Gotta say: I'm not a Harry Smith fan. I've seen his work over the years, and he just doesn't 'Wow' me.
Constructively, I would keep Hennig and Rotunda as a tag team, give them the "Fortunate Sons" name, and allow them to work on their mic work (Hennig, to hopefully improve significantly; Rotunda, just to polish).
I'd pair Colon with Yoshitatsu, as I like both talents, and give them the name "Immigration Act" and have them enter to "Immigration Song" by Led Zeppelin. Admit it, that would be pretty bad ass. The song would hype the crowd, then their solid ring work would put them over the edge.
Justin Gabriel-Heath Slater is a decent tag team. I think Skip Sheffield-Justin Gabriel is a better formula. I'm a huge fan of junior heavyweight-big man tag team pairings (a la Shawn Michaels-Kevin Nash). That is a great formula you don't see much of anymore. And this "golden ratio" is why I heavily disagree with WWE breaking up Curt Hawkins-Lance Hoyt. Hawkins-Hoyt would have been the team I would have pushed to the top if WWE had anything resembling a real tag team division. A year or two later, you break up the team, have them feud, see who's the bigger draw, and push that guy to the main event.
What WWE needs is a Junior Heavyweight title. And here's why.
Heath Slater should be working in a Junior Heavyweight division alongside TJ Wilson (I'd make his "Crown Prince" moniker his big heel gimmick), Low Ki, Matt Sydal; Chavo Guerrero, Jr. (to put over the younger talent), and bring up Richie Steamboat.
I'd future-endeavor Darren Young. He has no place on WWE's roster. He, Shad, Chris Masters, Joey Mercury, Luke Gallows, Tyler Reks, and the Dudebusters (Caylen Croft and Trent Baretta) should be released to free up monies. Kofi Kingston and Zack Ryder could easily feud with, and be used to put over, rising talent in the Intercontinental and United States divisions. Tyler Black: Bring him up as a foil or ally for CM Punk, or better yet, have him work a program with Christian. Christian himself should be a name in the main event. He could put over talent and be used to briefly hold titles.
WWE may want to make an effort to sign back Kurt Angle. Have Kurt Angle help Jack Swagger find the inner "All-American Rapist" shit-eating grin he lost. Have them team, the shortly have Swagger beat-up Angle. Chirpy, smug heel Swagger would be a lot better than "Why so serious?", poor man's Chris Jericho heel Swagger. A Swagger-Angle feud would be a great way to introduce Angle as a face, and help legitimize Swagger as a heel.
I would turn Sheamus to face and have him feud with, a heel, Wade Barrett. Add in a, face, Vladimir Kozlov if Barrett needs to beat-up someone. Add in, a heel, Ezekiel Jackson if Sheamus needs to beat-up someone. This would be a great way to build Sheamus and Barrett as characters.
If WWE turns John Cena to heel, I'd have John Morrison complete the loop and feud with the Miz. Here's what should transpire. A heel, Miz (who lost his Money In The Bank title shot) should feud with, a face, Morrison until both guys are assaulted by, Nexus members, (World title-holding) John Cena and David Otunga. Cena gives a generic reason, like "It's time to rid WWE of piss-soaked diaper-wearing babies", and Otunga just nods and laughs. In this feud, Miz turns face and Otunga jobs a lot. At the end of the feud, Miz-Cena (for a World title) is set up, and John Morrison pads out his resume, dominating Otunga in a short feud prior to a feud with/that would build up, new Nexus member, Mason Ryan. Otunga would be released soon after.
Later years mega-heel Chris Jericho, delightfully-smug heel Batista, water-spitting face Triple H, utterly-boring face Randy Orton, perpetual underdog face Rey Jr., The Undertaker, lovable Big Show, and Kane. In the interest of keeping the interest of fans drawn to popular names, feud Triple H with Batista. That should draw. Toss in a "tweener" Randy Orton to feud with both of them. This should happen on Raw. For SmackDown: Have Rey Jr. play underdog to Kane, and toss in the Big Show and Chris Jericho. The Undertaker? Use him less in his semi-active state. Have Undertaker draw Kane away from the Jericho-Rey Jr.-Big Show chaos, and let those two retire together in one, final match. Use a megalomaniac heel Edge in Kane's place.
Using the listed veteran talent, build Alberto Del Rio, Drew McIntyre, CM Punk, Bryan Danielson, Sheamus, Wade Barrett, Cody Rhodes, The Miz, Dolph Ziggler, and every other younger worker that needs it. I think that's what veterans should do, right?
In a world where I had full-control of WWE, this is what I'd do over the next 3-5 years.
