This is a real tough one. I like all three of these teams and if I could, I would push all of them. I personally think they all have talent, all have something different about them and when in action, they aren't bad. Of course, the WWE tag team divison is sorely lacking, but all three could definatley bounce back and make it good again. Anyways...
Push - The Usos
The Usos have been around since Summer 2010. When they debuted on Raw, they, along with Tamina, attacked the Hart Dynasty. This set up a small feud for the WWE Tag Team Championship and in the end, the Uso's lost and that was that. Since then, they are on and off the TV screen, but when they're on, they entertain me. With their background and their style, I think with the correct push, they could be quite popular. A heel turn would be nice, as many samoan's or superstars with samoan heritage are usually placed in this situation and pushed. Umaga, Rikishi for a short while, The Rock until his popularity rose, and others. I would love to a see domination from the two in a heel form, but not a cheap heel form, because I think their size and capability can speak for themselves. I'd like Tamina to join them again and turn her heel. Good team in my mind.
Job - The Prime Time Players
I like them. I like their cocky attitude and their in-ring isn't that bad for a freshly made team. AW in their corner isn't a complaint I will make either. But, I feel they are too fresh to come on the scene and just take the WWE Tag Team Championship. Past teams have done so, but the teams "gimmick" or whatever it is doesn't quite fit the bill of dominating and impactful. A team like this can and needs to progress. I think they will and they will be noticed. In time they will make it to the number one contendership again, but this time, don't just win a Fatal-4-Way Match, get them winning constantly and make them look good first. Then, I would push them.
Fire - Primo and Epico
I like this team too. Rosa Mendes is also quite nice, but out of the three teams, they seem the weakest, which is funny, because they are the only team to have won the WWE Tag Team Championship. I like the look, the matching tights, the pretty girl in the corner, and I certainly wouldn't want to fire them, but if I had too, I would because they don't do it for me like the others. I admit, they aren't bad in the ring and when put with a team like Evan Bourne and Kofi Kingston or Justin Gabriel and Tyson Kidd, they are bound to put on a high-flying show, but nowadays, that doesn't get over too well with the general audience. Sin Cara is a prime example. He is good in the ring when he doesn't botch, so look past before he got injured, but the crowd aren't totally behind him because we don't get to see the impact others show us. Just my opinion.
