It's probably not a coincidence that the promo ability of people from NXT noticeably fell off a cliff when Dusty wasn't there anymore. It's crazy they don't just make part of training at the PC having them study promos from all the footage they own. Or give one of the legends they work with stop by and give a class or two. You'd know Foley would be down, he'd do anything for a gig.
Come to think of it, it's actually amazing anyone in NXT can do a promo at all considering the main people in charge now are Hunter, King of the Boring Ass 20 Minute Promo and Shawn "was really great at a lot of things but talking wasn't one of them" Michaels.
