I don't think there's any question the Briscoes are being set up to have an enormous run with the tag titles. The only problem is if they did win it there would be no credible challengers at the moment save for throwing a few teams together and letting them challenge, or have some temporary teams (i.e. Jacobs and Albright) have a few challenges now and again
To be honest I really wish Rave and Shelley had won the tag titles earlier this year from Aries and Strong, they were a great tandem and together with Nana they were arguably the best thing on the show. Thinking about it I wouldn't mind seeing Shelley and Sabin team up like they do in Zero-1, *if* Shelley ever comes back, which is kinda doubtful
But yeah, before I got offtrack on that paragraph, Jimmy Rave has been consistently solid for a good 18 months - 2 years now, once they iron out his new character and where he's headed, I can see him winning. Nigel I'm not sure about, I think his touring with NOAH might hurt his chances a little bit as he often misses 2-3 shows in stretches. He would definitely be bought as a credible holder after the series with AmDrag, but I can't see him beating Homicide, I don't think it would gel right.
As for anyone else...Strong could definitely have a shot. I'm thinking giving him the FIP belt is Gabe's way of testing the waters to see if he can carry himself off as a champion, if he makes a good job of it I can totally see him getting a run. If that happens I'm just hoping for an Aries heel turn
To be honest, those guys aside I'm not sure if anybody else would really be bought as a credible challenger, unless there's another situation like with Gibson where a guy comes down from the majors for a while and gets over (Albright?). I'm thinking this year Whitmer is going to get a main event push though, Gabe just will not give up on him (and to be fair he has been accepted after the CZW wars) and he'll get his shots, although I don't think he'll win.
