The references
WWE is a wrestling promotion that feeds on its past glory. Although the company might not admit it, that is the truth. WrestleMania 32 was a major example. WWE had names like Shane McMahon and Triple H on top of the card and it is them that got the biggest pops of the night. This exposes the love that WWE fans have for the past stars.
And what Vaudevillains could do is: they could make references to Eddie Guerrero. The team has been drawing a comparison to Eddie Guerrero and Cesaro in terms of their looks and they could utilize this to get some leverage. Two new rookies comparing themselves to big names like Eddie and Cesaro is bound to get some heat and it could help them to establish themselves as a top heel tag team.
