Which former superstars should WWE rehire or ignore in 2020? The dream is to make it to the WWE and unfortunately for some, they don't get to stick around for one reason or another. However, when fans see one of their favorites return to Raw, NXT, or SmackDown, it brings a whole other level of excitement.

While away on the independent circuit, some wrestlers are also able to reinvent themselves and come back with more star power, causing them to end up in a better position on the card. However, some wrestlers just don't fit the WWE mold and won't succeed in the company for specific reasons no matter what they do. Without further ado, here are five wrestlers WWE should re-hire and five they shouldn't.

10 Should: Carlito

Carlito was one of the best mid-card acts in the Ruthless Aggression Era but WWE dropped the ball. He still is wrestling all around the world and wrestling some of the bigger names in the independent circuit. Although a comeback is unlikely, considering how WWE treated his cousins Primo and Epico, it would be nice to have a part-time run with Carlito winning the 24/7 Championship by spitting an apple into the champion's eye.

9 Shouldn't: Alberto Del Rio

Alberto Del Rio should not be in WWE ever again. The former WWE Champion is currently 43-years-old and has seen a lot in his career, but he has not shown the professionalism after his last run with the company. After seeing the fallout with his relationship with Paige, he seems to be an all-around bad guy and the risk is not worth the reward for WWE. Yes, there could be a few solid matches but the current roster has numerous great wrestlers that he will block with his position on the card. There is no reward for WWE to re-sign him. His gimmick has also become notoriously bland over the years.

8 Should: Damien Sandow

Damien Sandow was one of the most underutilized wrestlers in WWE when he was a part of the roster. He was able to do comedy incredibly well with his Mizdow character and be serious in the ring with his "Savior of the Masses" character. With a complete overhaul of his gimmick, he wrestles as Aron Stevens and is currently the NWA National Champion. Stevens is thriving in his role on NWA Powerrr and, if he wanted to return to WWE, he probably would return to the same spot he held previously. But Sandow's entertainment value and in-ring skill will make viewers tune into whatever he is doing regardless of how he's booked on the card.

7 Shouldn't: Trevor Murdoch

Trevor Murdoch doesn't fit the WWE mold as he doesn't have the look or physique as someone like Randy Orton or Roman Reigns. That's not to say Murdoch isn't capable of being a singles star but Murdoch is known more for it. He made it the finals of the NWA World Television Title Tournament and is predominantly a singles wrestler in NWA Powerrr. Maybe a singles run in WWE would be nice but it would be hard to see him in the ring with the upper echelon of WWE talent. WWE does not prioritize tag team wrestling like other promotions so the fit would be questionable at best.

6 Should: CM Punk

A Punk-WWE comeback probably won't happen, but never say never. CM Punk is still a huge name in the world of professional wrestling and could move the needle as WWE's ratings continue to plummet. Punk regularly played the role of a special guest on WWE Backstage, so there is at least a relationship by association.

The dream matches for Punk in 2020 are countless and, no matter the role, his appearance alone is worth it. Punk and WWE have a tumultuous relationship so as unlikely as it is, money talks. WWE should do whatever it takes to bring CM Punk back in a part-time role and give him a live microphone. Who wouldn't want to see the Straight Edge Savior creating yet another pipe bomb moment?

5 Shouldn't: Chris Masters

Chris Masters never hit that next level and was stuck in the lower mid-card while in WWE. He had multiple stints in the company and has been constantly wrestling on the indie scene before the pandemic struck. Masters has challenged for the WWE Championship in the past, but he didn't do much outside of the Master Lock Challenge.

Masters spent some time in TNA/Impact Wrestling while away from WWE, but he hasn't been able to find success there either. He is a middle-of-the-road wrestler and could be special with a manager by his side. The money and quality of work are better if the two sides stay away from one another.

4 Should: Chavo Guerrero

Chavo Guerrero is one of the best cruiserweights of all time and has proved his worth in gold inside of the ring. Guerrero spent a decade in the company and was given his release in 2011. He has been wrestling regularly but has yet to get into the ring in 2020 as of this writing.

He has been a staple of Lucha Underground in its four seasons. Guerrero could be a valuable asset for the younger talent and would be great for a little NXT run but he is 49-years-old. A limited run would be a great way to send off the legend into the Hall of Fame.

3 Shouldn't: Santino Marella

Santino Marella was one of the better comedic wrestlers that WWE has ever had on their roster. However, they sometimes attempt to be "too cute" with his character. Santino and his Cobra don't need to be returning outside of the occasional one-off appearances. Marella is only wrestling a handful of times a year since he walked away from the company. The two-time Intercontinental Champion could be a valuable backstage road agent to help the younger wrestlers with adding another layer to their character, but the WWE Universe seeing him wrestle inside a ring doesn't need to happen again. No knock on his work or anything, but it's better if he stays away from a WWE ring in 2020.

2 Should: RVD

RVD is a grizzled veteran in the ring, growing up in ECW and having some wild moments throughout his career. If WWE signed him to jump-start their mid-card as a SmackDown version of what MVP is doing with Bobby Lashley are doing on Raw, that would be a good situation for him. Also, it's incredible to imagine the formation of RVD and Matt Riddle as a tag team, two laid-back personalities that could kick ass and take names in the ring. RVD is still an active wrestler today, mostly competing on Impact Wrestling shows while making an occasional indie appearance. Even as a backstage road agent, RVD could do wonders for the younger talent that grew up idolizing him.

1 Shouldn't: Tommy Dreamer

The House of Hardcore promoter doesn't need WWE and WWE doesn't need him inside their ring. Dreamer is a respected name around the entire wrestling industry, but he fits better in a hardcore role rather than a sometimes cringe-worthy PG Era of WWE. That isn't to say he is a one-trick pony but most hardcore wrestlers have difficulty adapting to a WWE product. Unless you are Mick Foley, there isn't much room in WWE for the hardcore style and both parties could make a lot of money away from one another.
