I miss the old John Cena as well, I truly thought coming off the heels of Wrestlemania 20 he would be the next Stone Cold, a thug Austin so to speak. I loved Cena when he terrorized Brock Lesnar, Zach Gowen, Taker, and Brian Kendrick. And Cena is MUCH better in the ring than people give him credit for, watch his matches in OVW or on the independent scene and you will see he could be one of the best brawlers in the business, he just don't work well with the WWE style. I think if he is giving the ability to shine, Cena and RVD will tear the house down at One Night Stand.
Another person they have truly screwed over is Randy Orton, who yes has the emotional stability of a 10 year old girl, but is very talented none the less. Triple H basically ruined him in the feud after Orton one the title, and it was then that he started throwing fits and tantrums backstage. The whole reason he got suspended was because he kicked a door down when he found out he was the one taking the pin at Wrestlemania 22.
And why they couldn't sign Samoa Joe I'll never figure out. Umaga is god awful.
