This week's episode of WWE SmackDown will see the aftermath of Survivor Series: WarGames. It will also decide John Cena's last opponent, as the final of The Last Time is Now Tournament between Gunther and LA Knight takes place tonight.Compared to RAW, the blue brand's show has been underwhelming lately. To improve the show's quality, WWE must do these five things on tonight's episode of SmackDown:#5. Let Solo Sikoa shineOn the latest episode of RAW, Solo Sikoa faced Gunther in the semi-final of the Last Time is Now Tournament. It was a hard-hitting back-and-forth match that was praised by everyone. While The Street Champion lost the bout, his performance was impressive. Many called it the best singles match of Sikoa's career. iBeast @ibeastIessLINKSolo Sikoa is an elite performer man. One day he's going to get his appreciation. That was an amazing match.The Triple H-led creative team should capitalize on the hype Gunther vs. Sikoa generated and allow the Samoan star to shine on SmackDown. He should be booked in a singles match that is given ample time for Solo and his opponent to put on another instant classic.#4. Jade Cargill needs a credible challengerSince winning the WWE Women's Championship, Jade Cargill has yet to find a suitable opponent. The Storm had been involved in mini programs with Michin and B-Fab, and last week's SmackDown teased a rivalry between Cargill and the Women's United States Champion, Chelsea Green.Involving both women's champions of the brand in a rivalry risks hurting the credibility of the entire division, as other female stars would not get an opportunity to shine. Jade Cargill needs a credible babyface challenger, and Green needs a separate rival as well. The Triple H-led creative team should kickstart new rivalries for both champions on tonight's episode of the blue brand's show.#3. Put Drew McIntyre in a meaningful rivalryDrew McIntyre was on the winning side as part of Team Vision at Survivor Series: WarGames. After losing to Cody Rhodes multiple times, The Scottish Warrior needed a major victory.McIntyre should carry the momentum into his next rivalry. Either he could challenge Rhodes again after defeating his team last weekend, or he could start a new feud with another major star. For that, Nick Aldis will have to lift the Scotsman's suspension first.#2. Showcase a more aggressive version of Cody RhodesCody Rhodes has increasingly been more and more aggressive lately, which is a welcome change for The QB1's character. After losing at Survivor Series: WarGames, Rhodes should continue showcasing his aggression on SmackDown.The American Nightmare's second reign as Undisputed WWE Champion has been lackluster thus far. To ensure it gains fans' excitement, adding an edge to Cody's character seems to be a wise decision.#1. Roman Reigns should appear on SmackDownAfter the Men's WarGames Match last weekend, Roman Reigns shared a wholesome moment with CM Punk. However, as they both turned to Cody Rhodes, things got a little intense between The QB1 and OTC1. Reigns claimed that it was the last time he ever teamed up with Rhodes.WWE may be heading toward a third match between Roman and Cody. To raise the excitement for it, The Head of the Table should appear on SmackDown and confront The American Nightmare.
