Any time WWE wants him to, John "Bradshaw" Layfield (JBL) could set down his hat, slide off his headphones and deliver one last great match.
In an era filled with part-timers, JBL would be a welcome addition for, in the words of Christian, "one more match." While he was never the most fantastic worker, JBL could tell a mighty compelling story inside a WWE ring.
Brawling, brutality and palpable arrogance were JBL's trademarks in his prime and in the right situation he could use those traits to put on an awesome show.
Must like the way that Booker T stepped away from the announce desk to jump into a short feud with Cody Rhodes at the end of 2011, having JBL come out of retirement temporarily could help an up-and-comer in need of a worthy rival.
At 46 years old, JBL has plenty to teach a young guy.
Combining his experience with the raw ability and energy from someone on their way upward with the company is a recipe for an explosive match. Want to bring out Kofi Kingston's dormant aggression? Want to have Miz grow as a performer?
The self-proclaimed wrestling god is your man.
Travel back to SummerSlam 2008. On his way to megastar status, CM Punk fended off JBL in an excellent clash for the world title. JBL gave Punk a major challenge producing an entertaining match in the process.
Five years later, JBL can do the same with another dance partner. He'll prefer not to bang heads with his foe and darken his hair with blood this time though.
The novelty of seeing JBL return helps amp up a potential match before it starts.
Nostalgia is a powerful force among WWE fans. Goldust got an emotive response when he showed up at this year's Royal Rumble. Fans even took to seeing a 52-year-old Brooklyn Brawler return to action at TLC 2012.
JBL can do a lot more in the ring than Brawler can at this point.
His mountain climbing has to keep him in pretty decent shape, but JBL will undoubtedly be rusty. As fit as The Rock was, he showed a significant amount of ring rust during his recent return.
The thing is, a JBL match isn't going to be a great workrate bout. It's going to be a fight and JBL has the experience, know-how and vicious clothesline to deliver one slobberknocker of a fight.
A single serving of JBL-brand brutality would boost the entertainment value of a future WWE pay-per-view.
