Breakker vs Lesnar? Nahhh I can't see it. At the same time though WWE drastically needs to push new talent. They move at a snails pace with literally everything.
Cena and Roman are pretty much done in WWE, Lesnar is a part timer, and Cody has no credible main event opponents long term. The Vision is a dead stable without Becky.
This is all in the midst of major fan discontent + the Saudi deals + higher PPV costs + high ticket prices + aggressive advertising. WWE is not even in a position with this roster to book banger cards month over month right now even if they wanted to. Everyone has already faced everyone and there's nothing fresh available, which is why Jericho should just jump ship back to WWE, he'll have an easy main event spot.
Things are coming to a head and will reach a boiling point soon, and I think WWE will be forced to change their philosophy and method of operating somewhat. You can't rely on legends forever. They really need to deliver at next year's Mania before they go to Saudi Arabia the following year, and in my opinion I think this really needs to be the crux of the weekend:
Cody/Punk - Punk needs to turn heel and they need to retcon his feud with Rollins, no other way around it. Its over. Have Punk pin Rollins somehow without him winning the title and move on. Put Punk on an undefeated streak of sorts as a pissed off heel.
Lesnar/Gunther - Obvious money match
Roman/Breakker - Time to elevate a new top guy, Roman needs to take the L
Rollins/Fatu - Retcon the Punk & Zayn shit and move Fatu to RAW, establish a new guy and just have Fatu lose to Rollins at Mania if need be, at least you're making a new main eventer/credible guy
AJ Lee/Roxanne - Obvious for the IC title, home-wrecker feud
Vaquer/Ripley - Biggest women's match available
If that is not the meat of your card or something close to it, then anything else will probably be a bust knowing WWE.
