#1 Have Brock Lesnar cash in

Of all the things WWE needs to do in two weeks at Super ShowDown, the priority should be to get the briefcase of boombox Brock Lesnar. Not only would the moment serve as a show of good faith to The WWE Universe, but it also eliminates Lesnar from the title picture for the foreseeable future.
At least this way, WWE admits that Brock Lesnar getting the briefcase was a mistake, Rollins can thwart his cash in and look stronger than ever before. Either that, or WWE can go back their old playbook of having Lesnar win and hold the title hostage for months, but they do so at the risk of alienating their audience.

In the end, their best option is to have him cash in on Rollins or Kingston and have the attempt thwarted by the other champion. Or maybe even Triple H could thwart the cash in and start a feud with Vince McMahon over control of the company. All WWE has to do is get the briefcase of Brock, and it's all smooth sailing from there.
