The experiment with the 40-man Royal Rumble Match that year was decidedly a poor one. What was even poorer was the choice of winner. Alberto Del Rio must be considered one of the biggest busts in WWE history. He was never able to draw heat no matter what he did and his WrestleMania match with Edge that year, which he lost, was very much an afterthought.
CM Punk, in the meantime, was slowly accumulating heat and would go on to explode that summer. A Royal Rumble win would have only helped that heat.
Sure, the return of The Rock complicated the main event picture that year and John Cena vs. The Miz was done only to set up the eventual mega match between the two for next year's WrestleMania, but all the same, CM Punk's presence would have been far more preferable to what occurred.
