Damn... 400 Days....
What an impressive title reign. Part time or not, there's absolutely no shame in dropping the title to one of the biggest stars ever in the industry. Plus, there's obviously the very likely possibility that he'll get it back before the end of 2013 anyways
I'd much rather Punk take the title back at the Chamber or retain at the Rumble if it means we get Rock-Brock instead of Cena-Rock II. Personally, I think Rock knew who his Mania opponent was likely a year in advance, and if the WWE knew they probably would have waited until the second Rock-Cena match to put out a 'Greatest Rivalries' set, instead of opting to release the 'once in a lifetime' set.
Rock-Brock main events Mania. Title or no title.
