4. Bobby Lashley

A physical specimen, an athlete with a proven record, an ex ECW Champion. And then you think what the hell has he been doing ever since he came back.
The only strong impact he had was when he beat Roman Reigns clean but then even that was taken away from him as Roman Reigns beat him the subsequent night. He's meandered listlessly from one useless feud to another and now all of a sudden he's turned heel for no reason and even then not much is happening.
Top WWE star punished? More details HERE
When Bobby Lashley stepped into WWE some great matches were lined up like him vs Braun Strowman or vs Brock Lesnar but there haven't been any of those and his second stint could be termed borderline "Boring" with the lack of action surrounding him.
Bobby was promised the stars when he stepped back into WWE. A feud with Brock Lesnar was talked about. But he has been grossly sold short by WWE and if things don't change soon he could be looking at other avenues.
