I still don't understand why the got rid of Antonio or Adrian as first names, they both sound much worse as singular names.
I'm pretty sure Vince went through a phase where he thought short/single word names were the new big thing. Antonio Cesaro became Cesaro. Adrian Neville became Neville. Big E Langston became Big E. There was also that short push where they wanted to call Kofi Kingston "Wildcat".
