2011 was such a great pay-per-view year in retrospect:
Royal Rumble has Edge/Ziggler which was a MOTYC candidate. Royal Rumble match was good too. Booker and Diesal returning was fantastic
Elimination Chamber had two of the best Elimination Chamber matches in history, and even the Miz/Lawler match was fun. Also, Trish and Christian returns
Extreme Rules was a fucking FANTASTIC show. Cena/Miz/Morrison Steel Cage, Orton/Punk LMS, Rhodes/Mysterio Falls Count Anywhere, and of course, Del Rio/Christian in a great ladder match. Also, Kharma debut! Underrated pay-per-view, and one of the best ever
Over The Limit, while overall was a pretty average show, featured a MOTYC in Orton/Christian which alone makes that pay-per-view worthwhile. 17 minutes of pure, FUCKING AWESOMENESS
Money In The Bank 2011 was of course one of the GOAT PPV's featuring the lead up of the greatest angles in wrestling history. Perfect pay-per-view top to bottom. Bryan winning that case in a fantastic MITB match, RAW MITB was pretty good too, Orton/Christian was solid, and of course, Cena/Punk was absolutely amazing.
SummerSlam 2011 featured a REALLY AWESOME opening tag match, Bryan/Barrett was EXCELLENT as was the Orton/Christian Street Fight, and Punk/Cena managed to conjure up a magnificent match up once again that featured a weak finish, but Del Rio walked out with the strap.
Night of Champions had a pretty good Del Rio/Cena match, and an awesome Triple H/Punk match. Mark Henry beating Orton after MONTHS of being booked as a monster heel was a great moment.
Survivor Series was in MSG. Nuff' said. No but seriously, I recall the Ziggler/Morrison match up being great, Team Barrett vs. Orton was solid with the right person going over, Rock/Cena was electrifying with the crowd going nuts, and Punk/Del Rio was a great match with a feel good moment for CM Punk regaining the title from Del Rio in MSG.
Overall, probably best PPV year in company history. In terms of match ups, we had GREAT ones that year.
