#1 Kevin Owens as special guest referee
The highlight of this week's SmackDown Live was Kevin Owens' incredible promo against Shane McMahon, which began when Owens and Dolph Ziggler brawled before the start of SmackDown.
Owens' feud with Shane could be the start of the end of Shane's "best in the world" gimmick, and this rivalry could be furthered by adding Owens as the special guest referee in the tag team match between the team of The Undertaker and Roman Reigns against Shane McMahon and Drew McIntyre.

Owens is currently not on the Extreme Rules card but could be added to the card late in the day, to make matters even more interesting. Owens is now a babyface over on SmackDown, which was a much-needed change, and going up against a devillish heel like Shane will only help elevate him further.
