#4 Lashley
If you are judging Lashley by the way he's been booked on RAW, I'd recommend that you go and watch his Impact Wrestling heel run. Lashley is a beast in his own right and like Lesnar, also has legitimate MMA credentials to back him up. And now, he also has a hype man! One that can be annoying and entertaining to an equal degree for the whole WWE Universe.
Lashley vs. Lesnar is a feud that many have wanted to see. Lashley has gone on record to talk about it on numerous occasions. With Rush by his side, Lashley may be given a heel push and made into a top heel.
If Lashley does cross paths with Lesnar and destroys The Beast when the men clash, it could be a passing of the torch. This is, of course, provided the WWE Universe does not sour on him.
