Khali is terrible.
The problem with Cena is that although he is capable of putting on a good match, the suspense is gone as nobody believes he is going to lose a match.
Orton however will beat him at the next event, through dastardly cheating means.
If not thats 3 clean wins in a row for Cena in this feud and Ortons credibility is gone.
With the recent suspensions, deaths (Benoit, Guerrero) injuries (HBK, Lashley), retirements (RVD, Big Show) and people jumping to TNA (Angle and Christian) they need a new big star and strong rumours suggest Chris Jericho will be back in the ring next month. That will be something to watch, the best cocky asshole character ever in my opinion.
I personally think the biggest loss of recent times was Kurt Angle, a great wrestler and brilliant character, be it good guy or bad.
Now that HHH is back they need Cena to lose a few matches to spread the list of evenly matched potential champions out a bit rather that have a "who does Cene feud with and beat next" list.
I'd have Cena, Orton, Kennedy, Triple H, Umaga, Lashley, Jericho and John Morrison all in that group.
Smackdown spreads it about more but lets be honest, its the secondary show, its all about RAW.
The sad thing about all this is that I'm 31
