Part of that is just that WWE has never really been a place for great, naturally-delivered promos at any point in their history. They had Jimmy Hart for a decade and he never had a single great promo, which is mind-boggling. They also didn't really let Nash loose until his last six months or so with the company in 1995-1996, which is funny because he was more of a draw for them in those months than he was as champion. There are exceptions in all-time great promo guys like Randy Savage, Jake Roberts, and Roddy Piper. But most of the time, you have Bret Hart doing canned lines about "preparing yourself to be excellently executed!"
