I've heard and seen this before ... new teams are being introduced and we all think the tag team division gets a revival only to be pushed again a few months later with teams being disbanded. It's a rise and repeat scenario that has not changed for years. So unless I really see any tangible long term and consistent commitment to the division I am going to remain skeptical.
This pretty much sums it up. Don't count on the tag divsion being any better now than it's been over the past ten plus years. Let's take a look at the teams mentioned in the op.
More focus on the group as a whole than the tag titles
Decent team. Hard to suddenly start caring about them after three years of doing nothing.
Decent team. Potential as faces.
Two floundering singles wrestlers with nothing going on so they are suddenly a tag team for no reason. Likely won't last more than a few months. Hard to get behind a team like that.
Ok but seen more as a comedy gimmick than a threat in the tag division.
Comedy jobber team with more focus on the group than any particular team
Likely to be a comedy jobber team
More focus on the group as a whole than a tag team
I'm not seeing a whole lot to be excited about. Back in the glory days of tag team wrestling a team's members were committed to each other and had the specific goal of becoming tag team champions. They weren't just two guys from a group that happened to challenge for the belts. They weren't two struggling singles stars with nothing better to do than become a tag team. For the most part the two wrestlers came in together as a team giving the impression that they actually wanted to be a team and the tag titles was a goal worth achieving.
You named eight teams. Not bad quantity even if the quality isn't really there. There have been times where we'd be lucky to see half as many teams in the division. The thing is with the disappearance of jobbers and squash matches these teams are going to work together all the time on Raw and Smackdown. Back in the day the Hart Foundation, Brain Busters, Rockers, etc. would wrestle jobbers every week. This allowed us to become familiar with them and how they worked together without burning through all the competition so quickly. We've talked about how so much televsion makes it hard to come up with fresh matches for ppv. It's even worse for tag teams since there aren't nearly as many teams as singles wrestlers. It's going to be hard to build a big tag match for ppv when they are forced to work with each other so much on free tv. I guess if we get past the idea that big matches and feuds needed to be built up for ppv and just enjoyed the tag team matches we get on free tv the division isn't bad. If you're looking for big drama, hype, and anticipation you're not likely going to find it in tag team wrestling.
