#2 Randy Orton vs Jeff Hardy in a No disqualification match
If anybody doesn't know what happened at Extreme Rules, let me tell you Randy Orton returned and attacked Jeff Hardy. At the moment, Orton is a sadistic heel, which means he can do anything to win a match. That's why it should be a no disqualification match.
The feud between the two veterans will be great to watch. Orton has played this heel role for so many times but the fans seem to accept him only in this character. Orton and Jeff go way-way back when Randy was a ruthless heel.
Also, we will see high-quality match. The Viper is strong, aggressive and bold with his moves while Jeff is high flying and always tries to bring something now on the table. Just compare Randy Orton vs Jeff Hardy to any other current feud in the WWE, you'll find the difference.
