#2 Lars Sullivan (SmackDown)
Lars Sullivan is the archetypal superstar for which "the Land of Giants" is famous for. He has the look and the build to immediately make an impact on the flagship brand as a main event talent. But why is SmackDown better for Lars Sullivan?
For one, RAW is filled with monster heels at the moment, with Brock Lesnar, Drew McIntyre, and Bobby Lashley all present on the red brand. Beside them, there is Baron Corbin and Authors of Pain.
Comparing this to SmackDown, there's only Samoa Joe, with Killian Dain making only sporadic appearances, and Big Show probably done with in-ring work..
SmackDown would be the perfect place for Lars to start off his dominant run on the main roster. A feud with Rusev for the US title could do wonders for him, and WWE could give him a run with the title before entering him into the main title scene.
