Ladies and gentleman, Brock Lesnar is your reigning defending undisputed heavyweight champion of the box office. In other words, Brock Lesnar is money.
Did WWE really need to sacrifice the entire Money in the Bank concept in order to either set up a match in Saudi Arabia or make Brock the new WWE Champion before SmackDown moves to FOX in October? He's Brock freakin' Lesnar. They could've just named him the number one contender at anytime; he didn't need a new lunch box.
Whatever the answer to that question, it doesn't matter. Brock has the briefcase, so we'll figure out somehow to make his run with it something good and, above all else, something different. Brock himself is different than everyone else, after all. A standard cash-in is not for him.
We already saw Brock winning the contract after everyone busted their asses in the Ladder Match (looking at you, Finn Bálor) and yelling "that's too bad" with a smirk on his face. The guy already has a bad reputation for being a part-timer, so let's embrace that heat and run with it. He's Brock Lesnar and he's here specifically to p*ss you off!
