#1 To not let another monster fall
WWE has always invested heavily in monsters, as reports state that Vince McMahon loves to see bigger men take to the ring and dominate smaller opponents.
Cody Rhodes' uncle is a WWE Hall of Famer. More details HERE.
Over the years, we’ve seen WWE develop some successful monsters such as Kane and Big Show, while others such as The Great Khali, Big Daddy V, and Braun Strowman have not been as successful.
Keith Lee is another man who is built like a monster, and NXT seems to have shifted their focus from his wrestling abilities to his power in recent months.
With that in mind, allowing Lee to win a Championship so early in his WWE career will allow him to get a taste of gold and also allow the company to test him with a Championship reign.
It will help them retain the interest of the WWE Universe, and not let him try and fail again like what’s happening with Strowman.
Lee is an incredible athlete, and the company seems to know that if they invest in him now, they will be reaping the rewards in the long run. Therefore, allowing him to defeat a man as good as Roderick Strong proves that he's in it for the long run.
