Now that Wrestlemania has come and gone, the World Wrestling Entertainment (WWE) has kicked off their new year with Monday Night Raw the night after Wrestlemania and Smackdown on Thursday night.  Here are the five best things to come out of this week on WWE:

1. Debuts, Debuts, Debuts

Monday Night Raw was filled with NXT stars making their debuts into the main roster.  Apollo Crews made an emphatic statement by taking down Tyler Breeze in his debut.  Enzo Amore and Colin Cassady-- also known simply as Enzo and Big Cass-- came out to lay the verbal smackdown on the Dudley Boyz because as Enzo says, "you can't teach that."  That ended with Baron Corbin making his Raw debut one night after winning the Andre the Giant Memorial Battle Royal by battling Dolph Ziggler to a double countout.  The Vaudevillains debuted with a successful victory over the Lucha Dragons on Smackdown to roundup the NXT debuts on the main roster.

2. New Number One Contender for WWE Championship and Huge Return

Roman Reigns may have capped off Wrestlemania with a huge victory over Triple H for the WWE World Heavyweight Championship, but it didn't take even 24 hours to find a new number one contender for his title.  A Fatal Four-Way match was set up to decide the new top contender for the WWE title featuring Chris Jericho, Kevin Owens, A.J. Styles and Sami Zayn.  Owens, however, made sure Zayn couldn't make the match and seemed the match would now be a Triple Threat match.  But a new contender was added to the match, the Swedish Uppercut Machine Cesaro-- much to the delight of the WWE Universe.  After Cesaro landed several huge uppercuts to his opponents, Styles came out on top as the new top contender to Reigns's title.

3. Shane-O-Mac runs Raw for the night

Even though he lost to the Undertaker in their Hell in a Cell match a Wrestlemania, Vince McMahon allowed a bruised and battered Shane McMahon to run Raw for the night.  After Shane came out to shake Vince's hand and thank the fans before limping away, but Vince didn't "want to be upstaged," so he allowed Shane to run Raw for the night.  Shane-O-Mac definitely made some noise by announcing the Fatal Four-Way match to determine a new Number One contender, and even more noise when he brought back Cesaro as a surprise entrant.

4. Cesaro is Back!!

After missing several months with a major shoulder injury, Cesaro returned as a surprise entrant in the Fatal Four-Way match that headlined Raw.  He then teamed up with new Number One contender for the WWE belt, A.J. Styles, to defeat the team of Kevin Owens and Chris Jericho.  It is safe to say the WWE Universe is truly excited for the possibilities now that Cesaro is back and healthy.

5. Zak Ryder Fulfilled a Big Dream, Though Shortlived

In a surprising turn of events, Zak Ryder surprisingly won the Seven Man Ladder Match to win the Intercontinental Championship who fulfilled a dream he has been working hard for twelve years, and in front of his father. As great as the achievement was, unfortunately, it was shortlived.  A mere 24 hours after his victory the Miz came out to challenge his title with his wife, the returning Maryse.  Thanks to a distraction by Maryse, Miz was victorious and became the new Intercontinental champion.  Though his reign was short, it was still a happy view to see Ryder win the title at the "grandest stage of them all."
