He replied to a fan who seemed to have hit the nail on the head regarding the direction of the title, They're burying it.
I kind of get why they did it this way. By giving it to Mathews, an inactive wrestler, they are effectively saying the title is inactive. This would prevent Sydal from being the last champion. It doesn't really enhance the career of a final champion, and since Mathews is no longer a wrestler, it ends there. I think this is their intent, unless this is some kind of spoof storyline against the U.S title in WWE.Why Josh Mathews though?
KotM Title wasn't unified with anything, Corgan deactivated it, ironically this was the same time the Grand Championship debuted.Makes sense now although would of preferred it getting merged with another title like they did with the KOTM when Lashley won all the gold before.
