I love Chavo Guerrero. He's a great wrestler, he has a lot of ability, and he grew up around this business.
Honestly, the Chavo Guerrero behind Vickie, is not the Chavo of old. That's a week, pathetic manager...for a manager. Yes, now in the WWE even managers need managers.
Chavo has put up with getting yelled at by Edge, Big Show, Vickie...he's been Choke Slammed, speared, FU'd, tombstoned, put through a table.. it would be so easy for WWE to run an angle where Chavo became sick of all the crap.
I think there could be a couple of weeks were it got really bad. Big Show and Vickie could continue their affair, and make it obvious because Edge isn't around anymore. Eventually Chavo could confront her about it, saying how she's cheating on her husband, and he wonders if she would ever do the same to the man that used to be her husband. Vickie would slap him and tell him that if he had a problem, he could take on Big Show. If Chavo somehow won...Vickie would call the entire thing off with Show. If not, Vickie would renounce all ties she has with the entire Guerrero family!
During the match, Chavo could lay out Big Show with a steal chair, grab a ring bell and knock him out. Then he could grab Vickie out of her wheel chair and throw her into the ring. He would look at her and say "Choose. Guerrero...or him." Vickie would get all teary eyed and appologize to Chavo and say how she was going to change and be a respectable Guerrero. Chavo would hug her, but then knee her in the gut and hit the Three Amigos. He would go up top, give the shoulder rolls, and hit the Frog Splash on Big Show. He could end it with "you are dead to me, and my entire family." And before he goes he could stare at the crowd and shout "Viva la Raza!" and beat his chest.
That, would be the return of the Guerrero.
Chavo could go on to beat Big Show in a freak David vs. Goliath match. He could then go on to challenge MVP for the IC title, but be constantly stopped by Vickie every time he went to gain momentum. Maybe, Big Show would get sick of Vickie eventually, and actually help Chavo to get rid of her by going to the board of directors or something. Then Chavo and Big Show would challenge Vickie to find anybody on the RAW roster to face them, and if they won, Vickie would be fired, on the spot. She would get a couple sell out heels, but in the end, they would give her up, and she wouldn't be able to find anybody to come to her aid, and would be forced to quit.
Chavo could then actually go on to do great things, since he'd be in the spotlight a lot in an angle like this.
