I don't rate him, I'll preface this post by saying that.
He has likeability in his demeanour, bordering on charisma. He is fantastically athletic.
He does not sell well in layers. He sells impact pretty well, but not fatigue, not injury, not struggle in my view. His offence is very weak looking, which is a shame at it is very cool looking. When you put him in there with someone like Ziggler, that's a stroke of genius because Kofi's athleticism looks like it packs a punch. However, the roster is not full of Zigglers. As a result, too often he doesn't look like a heavyweight contender. And I've always said, to make it as a top guy when you're seen as that much of an underdog and that much of a small man, you need to be very, very good to get around it - Jericho, Bryan, Mysterio, Guerrero, Michaels, etc.
Kofi is not of that quality, and is destined to be mid-card fodder for the rest of his career IMO.
