#2 Bobby Lashley
Regardless of the experience and talent he possesses, Bobby Lashley hasn't tasted any sort of success in the main event scene.
The All-Mighty's return was certainly refreshing, but the creative team failed to present him as a dominant babyface on Monday Night Raw.
Though he did have his fair share of success on the main roster, Lashley's victory over Roman Reigns felt like a start of something incredible for the former ECW Champion.
The former Intercontinental Champion tussled it out with The Big Dog at WWE Extreme Rules, with the two performers wanting to lock horns with The Beast Incarnate, Brock Lesnar for the Universal Championship.
After Extreme Rules, the two clashed again on Monday Night Raw for an opportunity to face Lesnar at SummerSlam, where Roman unfortunately reigned supreme over Lashley.
Even though Lashley came out winning clean at Extreme Rules, the three-time wrestling national champion got lost under the shuffle real quick and never really found his way out.
He eventually turned heel, paired with Lio Rush, and won the Intercontinental Championship, but certainly lost all his credibility as a top-tier force on the main roster.
