Re: Rey Mysterio & Sin Cara can save the WWE Tag Team division.
I like the idea, but I have yet to see Sin Cara work effectively in a tag match because WWE tends to go to commercial break during his Raw tag-team matches. Therefore, I can't see his offense or any offense that may require his tag partner. He is usually on the receiving end of his opponents offense after commercial break, attempting to tag out over and over because of it, and tends to have no interaction with tag partner (besides finally being able to tag out or tagging in for the finish).
It would be a good addition to the tag team division, but it will not save it as of right now.
