#2 Starting a new feud for Lesnar
With angry Brock Lesnar, there would have to be a target for his anger. While it’s feasible for Seth Rollins to foil Lesnar’s cash-in plans on his own, it seems more likely someone else would intervene and play spoiler.
It could be established Lesnar rival Braun Strowman, though matches between the two have been lacklustre in the past and Strowman has seemed shunted backwards by WWE on the whole. Another option might be Ali who vocally criticized Lesnar on social media for swooping in to steal the Money in the Bank briefcase in the closing moments of the match.
A returning legend may be more likely, though—someone who won’t feel out of place opposite The Beast Incarnate. Should Lesnar make good on the suggestion he’ll cash in at Super ShowDown, career rivals The Undertaker and Goldberg will both be in attendance, and it’s conceivable one of them could thwart him (maybe after he gets involved in their match). Triple H could also be a possibility if WWE opted to revisit that issue that had the company had previously touched upon from 2012 into 2013.
