Best Option - Drew McIntyre
Unlike Corbin, McIntyre is a main-event level heel despite losing to Roman Reigns twice. He has that 'It Factor' that just isn't evident in every Superstar. Despite that, McIntyre has been relegated to being a lackey of Shane McMahon for the last month or so.
Just like McMahon needs to go away, McIntyre needs to separate himself from McMahon in order to cut his own path of destruction. Corbin is more like the corporate lackey than 'the Scottish Psychopath'.
McIntyre is good enough at his job that if he was the one to take the title off of Rollins then fans would boo him because he's good at what he does. There would also be a portion of the WWE Universe that would love to see him win the title because of the work he has put in over the last five years. Despite being a heel, he'd likely get a 'You deserve it' chance if he won the Universal Championship.
