I rewatched all of the '05-'06 Smackdown! PPVs a few years back and they missed the card on some of those too.
Primo & Epico is the only other tag team that I can think of that had a ton of success, on paper, but got more ignored. I really don't think Primo & Epico made more than a PPV or two during their early 2010s Tag Team Titles runs.
Random fact: Primo & Epico may have been the last team to win the titles on a house show.
