If you ever hear a lot of their contemporaries talk about why guys like Shawn Michaels, Curt Hennig, and Bret Hart were the best workers of their generation (in the west), they usually start with "they never missed a spot."
It seems like the most simple, fundamental thing, but it's incredibly hard to always be in the right place at the right time -- to never miss your X, to keep the pace of a match going, to keep the story consistent by never missing, by perfectly executing everything from a back bump to a headlock.
Okada is this generation's perfectionist.
