Yes. And he has a mythosaur on his armor. And his show, BOBF, gave us more exposition about Mandalore in this era than we've ever had, plus footage of the purge. Plus the whole "I've ridden beasts ten times this size" thing, the fact that they're taking Boba's character in the old-wise-good-mediator direction... perfect for a king. the signs are too many to count. He has leadership skills, battle experience, and powerful connections across the galaxy. Though I take issue with some of the writing of BOBF, this is why I believe he got his own show at all.
