I don't want to be that guy either and I assumed Coach Mora was not a Junior. I don't believe he uses Junior in his name. However, I think it is actually up to the individual as to whether he wants to be named "Junior" regardless of his exact name. Announcers may get it wrong or they may just use Junior to distinguish between the two. I've seen it written that Junior is appropriate if the first and last names are the same. In the end I think it's a matter of choice. So it may be fine for announcers to use Junior if only to distinguish between the two.
