#4 WWE shouldn't bring back The Undertaker to compete

The Undertaker retired at Survivor Series last year, and while WWE has made it out to be the end of his career, there are always rumors floating of a return. Unfortunately for WWE, this would undermine any credibility they have left, and ruin one of the last few true legends in the company.
Think about it – WWE already teased The Undertaker's retirement at WrestleMania 33, but had him return on and off afterwards. While some of the moments were pretty special to witness, especially his Boneyard Match with AJ Styles, it wasn't worth the lost credibility to get there.
In the end, The Undertaker should be retired for good, and not used for anything beyond promotion. Whether that is a video game DLC character, or maybe as a guest host for WrestleMania is fine, but any kind of wrestling capacity should be out of bounds at this point. It's just too costly for everyone involved.
#3 WWE should bring back Ronda Rousey

WWE needs legitimacy in the absence of Brock Lesnar and Ronda Rousey might be the only one left that can help get it back. In all honesty, between her ever-growing social media following, and previous comments about the pro wrestling business, it's evident that WWE needs to get her back in the ring.
A big problem with the company lately has been their unwillingness to blur the lines between fiction and reality. Of course, the exception to this would be The Fiend character, but the rest of the roster is not capitalizing from that same success. It also seems like WWE is hesitant to blur the lines for some reason.
In the end, WWE needs to bring Rousey back, and bring up what she has been saying on Twitter. Not only will that enrage wrestling purists that don't like Rousey, but it will also attract mainstream appeal. It might even result in a match that could headline WrestleMania again.
