It would be interesting if WWE make this look like a big surprise victory for Barret. Every one including commentators, Bryan himself and other peers on the rooster (except for the Michael Cole, Core members and Barret himself), should play this as a surprise. Off course, Barret and other core members should show it as a routine victory for them, but everyone else should mock around it as if Barret has exceeded their expectations. They should show that they have been thinking of Barret as non-competitive, gutless, and not good enough when he has to compete alone. It would be really funny if Sheamus comes out (remember when Nexus started, Sheamus was the first one to call a truce with them) and tell Barret, that Barret has impressed him. If other members of the rooster, who have lost to Bryan cleanly make those compliments to Barret, it could frustrate and irritate Barret. And finally when some of the Divas (especially Bella twins) giving similar compliments, can really make Barret go mad
. Finally, his own Core members should play a harmless joke on him which won't go well with Barret, thus making him really desperate to prove a point. In the process, if he looses to any upper card superstar, it should make Barret look inside and doubt his own abilities. It can lead to some really awesome promos and backstage segments.
This can serve two purpose
-- It can make Bryan look like a big deal, and this Barret's victory over Bryan not going unnoticed. I know it has already been happening since NXT season 1, but it will ignite those war of words between Cole and Bryan, those issues between Bryan and other members of old nexus, and it will simply make sure that people notice it. I can see this as an opportunity to produce a compelling drama. In my opinion, they should have done this when Taker lost cleanly to Kozlov few years back.
-- Other than the leadership of Core, Barret (and other Core Members also) doesn't have any story and any sense of purpose. Excellent mike talent of Barret is getting wasted, and right now there is nothing in Barret's character to invest yourself emotionally in. This story should bring him to the limelight again. Also, it will give SD a much needed mid-card story (sorry, i don't find Mark henry vs sheamus feud interesting).
