Thanks to Dave Meltzer in the latest edition of the Wrestling Observer Newsletter, we now know that the reason Vince McMahon doesn't like NXT Superstar Matt Riddle is indeed because of the way he's been using social media to challenge main roster Superstars like Brock Lesnar and Goldberg.
Riddle has been highly critical of both men and even tore into Goldberg for his disappointing match against The Undertaker during last year's Super ShowDown match in Saudi Arabia.
Meltzer went on to say that Lesnar has serious issues with Riddle over the way he's conducted himself and the fact he has Vince's ear is likely what's led to this. Apparently, the WWE Chairman sees Riddle "as an outside guy and feels Riddle has no respect for the hierarchy of the business by challenging Goldberg and Lesnar."
As a result, Riddle is going to need to behave himself over the coming months or he risks being brought to the main roster and subsequently buried by the Chairman on RAW or SmackDown.
