#2 Stone Cold Steve Austin
Stone Cold Steve Austin will make his return to RAW next Monday, which is also the #316Day. It is unknown what exactly Austin is going to do on RAW, but WWE has two or three good options.
Firstly, they can have him make a comeback and celebrate the special day by taking out The Monday Night Messiah’s clan, joining forces with Kevin Owens and The Street Profits.
The second is to book him in the contract signing segment of the WrestleMania match between AJ Styles and The Undertaker. This may not be a popular option but WWE can take this route considering the fact they need to protect The Deadman from getting hurt. Styles could keep bragging about himself only for the two legends to take The O.C. out.
Finally, WWE can allow him to take 15-20 minutes of the show, talking about how special the 316 day and WrestleMania 36 is. He would later declare himself as the host of the event. At WrestleMania, the host could announce a stipulation for the match between Randy Orton and Edge. The third option seems to be the likeliest and could be the choice WWE makes.
