#4 Murphy
The problem with Buddy Murphy was always going to be that when he is not Seth Rollins' right-hand man, he is just another sports entertainer. And yes, he is a very good professional wrestler, but as we have seen in the past, that is not enough to make it in WWE.
Now that Seth Rollins is doing his own thing with Drew McIntyre, I have a feeling that Murphy will once again be relegated to the lower end of the card unless something drastic was to happen to him. And this could happen thanks to Zelina Vega who has made it a point to align herself with the most talented individuals in the WWE roster.
I can totally imagine Murphy and Garza as a heel tag team that goes after the Street Profits and actually have some excellent matches at par with the SmackDown Tag Team Division because of how good every individual in the program would potentially be. When the spotlight shines on him, Murphy is one of the best in between the ropes, in my personal opinion at least.
