It might have been 7 seven months, but why did WWE give him the belt? was it an experiment? i wonder this ever so often and think was WWE trying to kill themselves. After a while i started to think about what was happening in WWE at the time in late 2010. Well, i remembered Linda F'N McMahon was spending over 10 Million dollars on a senate campaign that she lost and her opponents aired footage of Vince McMahon forcing Trish Stratus to strip and bark like a dog. Also showing footage of the huge guys that were the main guys (Cena included) plus bringing back Benoit to the story. When news broke that Randy Orton had broken the wellness policy many times and was known for steroids WWE took what the opponents said to heart. Launching the "Stand Up For WWE" campaign which encouraged fans to defend WWE from false criticisms which also wasted a couple $10,000 of ads on Nick (which i still watch) When that happened they needed someone to take the belt nearly immediately, Cena is another feud and is huge, and they must have gone to the whole roster of stars and chose the one guy that had the "kayfabe" opportunity to get the belt anywhere and any time. That's how I think it happened.
