#4 Money
When Brock was fighting in the UFC he was indeed getting paid ludicrous amounts of money per fight - but the last two words are key to that sentence. In the WWE, Brock receives a standard amount and it isn't dependent on going inside of a cage and straight up fighting another man. Instead, he gets alot of money to make very limited appearances throughout the year.
It's not exactly a bad deal and there have been reports that suggest the fee he is paid annually is in the region of $6 million. That is an absolutely baffling amount of money no matter which way you look at it, and that kind of consistency probably played a big factor into Brock's decision to return to the squared circle. Either way, nobody can question his business sense.
From money to something that's a little more personal for the Beast Incarnate.
