Do add onto what Garden State said, the guy is top notch in the ring however he has no charisma, and probably does not have what it takes to be a star in the WWE. I believe that is why ROH originally pushed him to be the cornerstone of the company, back when they did.
As far as is title reign it's been....ehh. I think poor booking of him as champ, has more to do than Black not performing. I saw Steen vs. Black live and that was a great match. Probably one of his better defenses. Good fueds, just not many title defenses.
