Sami's obviously not booking himself this way and I'd point out that he has cut numerous excellent promos over the years, often as a heel, but he is certainly capable of more. If he seems boring, it's at least in part because he's been relegated to a secondary character (and by extension, so has the belt) in his first program as a champion. That's an impossible position to make work when the entire crowd is far more invested in Otis erupting on Gable.
