#4 A natural when it comes to cutting promos
There are many Superstars in WWE who are naturals when it comes to cutting compelling promos. Samoa Joe is certainly in the top-tier of Superstars with the ability to do the same. The Miz is also someone who is passionate, albeit in a very different manner. Maybe Bray Wyatt is in the same league, although his delivery is very different indeed.
We've also seen on WWE Backstage and the NXT Kickoff Panels that when it comes to the speaking game, Samoa Joe is certainly a class apart. It makes all the sense in the world that he would be natural on the commentary desk as well. From the little we have seen from Samoa Joe at the desk thus far, he really is a pretty great fit!
Maybe, much like Jerry Lawler, the second part of Samoa Joe's career would be as the voice of the Red brand.
