#4 Luke Harper
Let me first say that this selection all depends on the return of Luke Harper. He's made some recent posts via social media, which hint at a possible retirement, but until something is confirmed, I'm not buying it. With this said, the injury he sustained was fairly significant.
Back in March, Harper dislocated his patella and tore his medial patellofemoral ligament, (say that ten times fast) which put him on the shelf for at least 5 to 6 months, which means IF he comes back, he could return in the next couple of months.
Let's say Luke does in fact return. Imagine Luke Harper as a Paul Heyman Guy. Heyman likes these freak athletes and I have no doubt whatsoever that Paul could do great things as an advocate for Harper.
Luke Harper is already a solid in-ring performer. If he had Heyman by his side, it could potentially be something very unique and very special. This could be the long shot of this list, but what does he have to lose? He surely has a world to gain.
