Apparently Triple H didn't want to sign the two after their recent WWE tryout due to their size. The feeling within WWE right now is that the company has enough talent that isn't very big, but can "go" in the ring. Because of this mindset, the company was looking for guys who fit a different description in the most recent tryout camp.
A lot of people reportedly went to bat for Richards and Edwards, saying that not only should WWE sign them, but should immediately push them to the main roster. Ultimately, WWE decided not to sign the two.
