#2. Brock Lesnar interferes in The Shield match, special guest referee added
A lot has been happening in WWE in weeks past. So much so, in fact, the Universal Championship has been all but forgotten, truth be told. Which is why it may make sense for WWE to have Brock Lesnar interfere in the Shield vs. Lashley, Corbin, McIntyre match to make the WrestleMania match even bigger.
This may force Vince McMahon to add a special guest referee to the big match. One of the first names that comes to mind for a role like this is Shawn Michaels. It could potentially even set the stage for a contest between Michaels and Rollins somewhere down the line.
Having Lesnar square off against Lashley could also sow the seeds for a clash between the two bulls. Fans have wanted that match for many years now.
