#2 Randy Orton
Like Lesnar, Randy Orton was someone that was lucky enough to be on both SmackDown Live! and Monday Night Raw. While Orton himself was a great presence on both the shows, it was Paul Heyman that actually did the magic for Orton. Heyman underlined how vicious and unpredictable Orton is and this resulted in a huge pop for The Viper when he showed up on Raw.
Later on SmackDown, Orton renewed his battle lines with Lesnar and is slowly turning into a compelling character in the WWE roster. If WWE lets him be strong for the coming weeks, the Lesnar vs. Orton match at SummerSlam is bound to attract more eyeballs.
