We are only a few short weeks from the 2011 edition of SummerSlam. SummerSlam debuted all the way back in 1988. Since then there have been 23 main-events.
The 24th main-event will most likely be the champion vs. champion match between CM Punk and John Cena. I'm sure that match will immediately join the top of this list.
In the meanwhile, what I will do is rank each one and tell you what is the greatest main-event in SummerSlam history.
