Reigning, defending, undisputed MITB holder

[BoomPeriod]

So Brock knows that he can keep the briefcase for a year. Why not have people challenge him for it and he can get another undefeated streak but this time with the MITB, building him up to be a major threat again and getting some good matches we haven't seen yet along the way. 

I know probably a silly idea but would make his matches more meaningful and get more use out of him.

[Oh Cry Me a Screwball]

There is no feasible way that Paul Heyman would allow this to happen.
