Ok, not to sound like an ass but how do you not know how to spell technical?
Anyway, true, Joe is average at best. He's a decent speaker, but has zero charisma to elevate his character. His promos are like shoot promos, except we not it's scripted so it kind of makes them shit. His best promo was when he went off on Scott Hall for no-showing, because we found out it wasn't staged. Hell, anyone could have guessed it wasn't by Nash's reaction, so Joe is one of those guys, who like Punk, would have prospered in the old school ECW because in the TNA/WWE world, he'll be considered average at best because you either get over by having a great look, marketability or being charismatic. Joe is over in TNA due to his indy following, and stiff in-ring style, not to mention he can move pretty fast for a rounded heavyweight, but that would amount to nothing up North where WWE fans rarely watch ROH and other indy organizations. Let's say if he were to debut in ECW next week. At most, we'd hear a few scattered TNA chants and that would be about it.
Umaga is pretty much a lot like Joe, they are both athletic for big Samoan guys, and I would assess Umaga isn't very charismatic, either. Sure, he can play his character well, he's had years to perfect it, so he better, but in terms of charisma, I think he is just along Joe's level; he has none. I guess we'll find out when he starts talking, which I'm not very much looking forward to. I mean, after years of screaming in a native language, what excuse will he have to explain why he never spoke in English before?
