Interestingly, the placement of Rey Mysterio and Sin Cara on this list as a team represents different things for each wrestler. Neither made much impact as a singles performer in 2012, so it's as a tag team that the Mexican legends make the list at No. 21.
For Mysterio, this is a dramatic comedown from his usual year. Rey spent much of 2012 injured and out of action. When he was on television, he seemed to be used as fodder for up-and-coming heels instead of being a legitimate contender for any WWE gold.
For Sin Cara, who was rumored to be close to getting the dreaded "future endeavors" letter at one point in the year, his inclusion on this list as half of a tag team represents a reprieve.
Rey seems to be flourishing in his mentor's role, and working in a tag team limits his exposure to injury. Sin Cara's in-ring abilities have flourished in his time with Mysterio, and a run in the tag division might be the start of something bigger for the luchador.
Currently, the pair is slotted as the No. 1 contender for the WWE Tag Team championship belts, and will face Rhodes Scholars at TLC for the right to a match with Team Hell No at a future date. As the second-rated face tag team in the company, Rey and Sin Cara appear to be on the right track.
It's possible that the two will continue as a tag team, helping to elevate the division. It's also possible that this is the beginning of a feud between the two, as tag teams inevitably break up. Could we see Rey vs. Sin Cara at WrestleMania? Only time will tell.
