Hello I think it would be cool if Grado joined the WWE. I watched the reaction when he was on TNA British boot camp season 2 and when got to the UK final before the wrestlers were going to USA . Grado came out to like a prayer by Madonna and everyone and I mean everyone (men women children of all ages ) sang a long to the song. So he would get a favourable crowd reaction form the fans .
Furthermore he could be a good tag team champion or even US/ IC champion .
As with Jinder Mahal once your are in the WWE anything can happen .
