#3 Brock Lesnar
Brock Lesnar is known for his brute strength and his work over the years with the WWE has made him as the most sought-after performer. During the years he has been advocated by Paul Heyman as the biggest box-office attraction, and no one will be able to question that statement.
'The Beast Incarnate' is the force of nature, and during his two terms with the WWE, he has been great inside the ring. Brock Lesnar ended The Undertaker's undefeated streak at Wrestlemania, but before he defeated 'The Phenom' at the Shows of Shows, the current Universal Champion eliminated 'The Deadman' during Royal Rumble 2003 to win the match.
While he is the most loved performer in the WWE, he still hasn't entered the Royal Rumble match at #1, and going by the way his situation with the company stands, there are few to no chances of him entering the match at the first position.
