I've been thinking about Cena and Orton's dominance of the main event scence and of course, the world championships.
Now for these statistics I'm going to exclude Undertaker and Triple H since they are both considered "semi-retired" from in ring competition. Anyway, Cena and Orton have a combined total of 20 world championships between them, lets look at the rest of the roster. (ECW and non WWE championships are excluded)
Alberto Del Rio: 1 time WWE Champion
Big Show: 2 time WWE Champion
Christian: 2 time World Heavyweight Champion
CM Punk: 3 time World Heavyweight Champion, 1 time WWE Champion
Dolph Ziggler: 1 time World Heavyweight Champion
Jack Swagger: 1 time World Heavyweight Champion
Kane: 1 time WWE Champion, 1 time World Heavyweight Champion
The Miz: 1 time WWE Champion
Rey Mysterio: 2 time World Heavyweight Champion, 1 time WWE Champion
Sheamus: 2 time WWE Champion
As you can tell, John Cena and Randy Orton hold more world championships combined, than the entire WWE roster! What is more worrying is that John Cena has been champion at least once every year since 2005.
