Why Do They Love Corbin So Much

Baron Corbin has been relentlessly pushed for a while now, is there a reason I'm not getting? He dies not check the usual Vince boxes…

He doesnt have an impressive physique
His hair was so bad they had him shave it off
He's ugly
He isnt funny, or clever, or intimidating I, the mix; just boring
Bad wrestler

Why wont they just cool it with this guy already???

Two words:  Blackmail evidence.  Clearly the photos of Bret and Vince plotting the Montreal screwjob together exist, and Corbin has them.
